Since the Hawaiian Islands have already been discussed, lets discuss the number of animals found in the fossil record.

According to global flood advocates, the global flood is responsible for the majority of the geologic column and it represents the remains of the preflood world. One biosphere was destroyed in this global cataclysm meaning that all the fossils we find lived on earth simultaneously prior to the flood. Thus we should be able to look at the number of living creatures and determine if it is possible for all the animals to live on earth at the same time. If not, then the global flood model has a tremendous problem. Only one biosphere was destroyed but if more than one biosphere is represented in the record, then the single global flood model can't be correct.

What do we see? There are clearly too many animals found in the geologic column. This is from my book Foundation, Fall and Flood, and I also for the first time post the references with this extract. There is more discussion below the references

The following is from Foundation, Fall and Flood

****start***

Too Many Animals

Advocates of the global flood claim that all the fossils are the remains of animals that died in the flood. Morris states,

"Still further, the creationist suspects that the fossil record and the sedimentary rocks, instead of speaking of a long succession of geologic ages, may tell rather of just one former age, destroyed in a single great worldwide aqueous cataclysm."37

If this claim is true, that the fossil record represents the remains of a single prediluvial world, then there should not be enough fossils to overcrowd the world. Most animals would be destroyed in the Flood, not preserved. Thus if the geologic column consists of one single biosphere which was destroyed in one year, there should be very few fossils and certainly not enough of them to fill up today's earth. But this isn't what we see. What we see are too many animals, which means that we have buried in the geologic column more than one biosphere.
Whitcomb and Morris cite with approval a paleontologist who estimates that the Karroo Formation of southern Africa is believed to contain 800 billion fossil vertebrates with an average size of the fox.38 There are 126 billion acres on the surface of the earth. Only 30 percent of this area is land, giving a land area of 38 billion acres. If 800 billion animals were spread over the 38 billion available acres, there would be 21 animals with an average size of a fox, per acre, from this deposit alone. This does not include all the vertebrate fossil deposits throughout the rest of the world. Assuming that the Karroo beds are only 1% of the fossil vertebrates in the world (the Karroo beds occupy much less than 1% of the sedimentary column) means that 2100 animals per acre occupied the preflood world. Since an acre is 4840 square yards, each animal would have only 2 square yards, or 18 square feet, of territory. That is an area only 4.2 wide by 4.2 feet long. This can be put in a setting that most Americans can understand. The average house lot is about a quarter acre. Can you imagine every house in your neighborhood surrounded by 525 hungry animals the size of a fox? I, for one, would not venture out of doors. Obviously this is far too many animals. [I don't believe Morris' numbers but if they are right, then this is the consequence--grm]

Too Many Plants

If we further consider the quantity of plant matter which must have occupied the single preflood world envisioned by young-earth creationists, these results pale in comparison. There are an estimated 15 x 10^18 grams of carbon contained in the coal reserves of the world.39 An acre of tropical forest contains 525 kilograms of plant matter per square meter.40 Assuming an 18% carbon content of plant matter41 we have 94.5 kilograms of carbon per square meter. Multiplying this by the number of square meters on land, we have approximately the quantity of carbon contained in coal, 15 x 10^18 grams. One can account for all the carbon in coal only by postulating a tropical rain forest over the entire world.
But this is impossible, because many of the animals in the fossil record require low productivity regions to survive. Grazing animals that live on grass can not live in tropical rain forests, because carpeting grasses do not live there. Now we have too many animals on each acre and almost too much plant matter. But we are not through.
Whitcomb and Morris believe that oil and natural gas are the result of the decay of plants and animals that lived before the flood. These authors state,

"The exact nature of the organic material has been as yet quite unsettled, but there seems little doubt that the vast reservoirs of organic remains, both plant and animal, in the sedimentary rocks constitute a more than adequate source."
"Although the details are not clear, the Deluge once again appears to offer a satisfactory explanation for the origin of oil, as well as the other stratigraphic phenomena. The great sedimentary basins being filled rapidly and more or less continuously during the Flood would provide a prolific source of organic material, together with whatever heat and pressure might have been needed to initiate the chemical reactions necessary to begin the transformation into petroleum hydrocarbons. Of course, not all organic debris deposited during the Flood was converted into oil; apparently certain catalysts or other chemicals were also necessary, and where these were present, it was possible for oil to form."42

If all the oil were the result of the decay of organic matter, then there is far too much oil and natural gas in the world. There are 201 x 10^18 grams of carbon in the hydrocarbons of the earth. In all of the world's living things, there are only 0.3 x 10^18 grams of carbon. There is 670 times more carbon in petroleum than there is in every living plant and animal on earth. Surely the world was not 670 times more crowded at the time of the Flood than it is today!

Too Many Plankton

There are also too many microscopic animals. Most limestone is deposited by bacteria and invertebrate animals. The Austin Chalk, which underlies Dallas, is a 400-foot thick limestone bed made of the remains of microscopic animals, called coccolithophores or coccoliths. It is about 70% coccoliths. The coccolithophore is a small spherical animal, between 5 and 60 micrometers in diameter, each having about 16 coccoliths that separate upon the death. According to Stokes Law these animals would fall through the water at a rate of .1 millimeter per second. To fall through a 100 foot (33 meter) depth of water would take 4 days.
The time required to form the Austin Chalk is far longer than one year. The coccolith skeleton, when pressed flat, is about 1 micron or one millionth of a meter thick. A deposit of coccoliths 400 feet thick must represent many thousands of years of deposits. One hundred twenty-one million coccoliths could be stacked up like coins across the four hundred feet. The length of time necessary to deposit these 121 million coccoliths can be calculated by assuming the maximum density of living coccolithophores in the waters above. Such measurements can be made during an event known as a red tide.
Occasionally, growth conditions become so favorable that they grow beyond all reason. As many as 60 million creatures per liter of water grow and quickly use up all of the oxygen and nutrients in the water and then die. Their decay continues to use any oxygen entering the water and also gives off poisons. Fish who swim into one of these areas often die from lack of oxygen and the absorption of toxins emitted by the dead microorganism. These water blooms last only a few weeks as the microorganisms deplete the water's nutrients rapidly and die. However, even at their most dense, 60 million microorganisms per liter, only 39 layers of organisms are stacked in a single cubic centimeter. Thus, to stack 121 million coccoliths would require the death of nearly 8 million organisms. A 100 foot water depth, filled to the maximum with coccospheres, would only generate a thickness of six feet of chalk! The four hundred feet of chalk of the Austin formation would require 66 such blooms. If it required two weeks between each bloom to recharge the nutrients and one week for the bloom to occur, it would take 4 years to deposit the chalk. And these values are wildly optimistic for the deposition of chalk. This size bloom is not possible.
The coccolithophores remove calcium carbonate from the water to make their skeletons. In water depth of 100 feet there is not nearly enough calcium to deposit such a volume of chalk. One hundred feet of seawater contains only enough carbonate to deposit a little over 1-millimeter of carbonate. Thus, no bloom of the size mentioned above can even occur. Using the two-week recharge and one-week bloom mentioned above, it would take 7,000 years to deposit the chalk. Obviously, the chalk under Dallas would require much more time to deposit than merely one year. In southern Louisiana, the chalk is 2100 feet (640 meters) thick. I have drilled it. This would take considerably more time than seven thousand years.
Additionally, the quantity of chalk seen in the world is far too great to have been contained in the preflood world hypothesized by young-earth creationists. The Austin Chalk is a chalk deposit that stretches from Mexico along the coast of the Gulf of Mexico into Louisiana, a distance in excess of 800 km. In Mexico, the Austin Chalk is named the San Felipe Formation. A glance at the geologic data shows that the band is about 160 km wide and appears to average 120 meters in thickness.43 In the chalk in Texas alone there are enough dead coccolithophores to cover the earth to a depth of 3 centimeters. But Texas is not the only place on earth that has deposits of chalk. In Alabama and Mississippi, the chalk is known as the Selma. The Niobrara chalk - 5,000 km long, 1,400 km. wide and 6 meters thick - runs through much of the western part of the Great Plains of the United States.44 The Niobrara would add another 7 centimeters of cover to the earth. Throughout Europe Upper Cretaceous chalks cover large areas. The White Cliffs of Dover are made of chalk that is as much as 215 meters thick in parts of England. This chalk sweeps across southern Scandinavia, Poland and into south Russia where it attains an amazing thickness of up to 1000 meters. It is stopped by the Ural Mountains. The chalks of western Europe are enough to cover the entire earth to a depth of 83 centimeters.45 West of the Urals, in the Central Asian Tuar-Kyr mountain range, a deposit of chalk 20 meters thick is found. In Israel, Jordan, Egypt, Syria and Saudi Arabia, an Upper Cretaceous chalk is around 180 meters thick. If all the fossil record was the record of the destruction of one preflood biosphere, as Morris suggests, it must have been a crowded place. The worldwide quantity of dead coccoliths would cover the earth to a depth of one meter.

Too Many Diatoms

A deposit that is similar to chalk is diatomaceous chert. These siliceous deposits are made of little more than dead diatoms. A diatom is a small single-celled animal that lives in the sea. As diatoms collect on the ocean floor and are buried deeper and deeper, they are compressed and changed from a form known as diatomite, which is used in swimming pool filters, to opal. Upon further burial, with increased temperature and pressure, the opal is changed into chert. The Monterey formation of California is such a deposit. It is the light-colored rock that forms much of the landscape of southern California. The deposit is 1,200 kilometers long, 250 kilometers wide and averages half a kilometer in thickness. This single deposit of dead diatoms is large enough to cover the earth to a depth of nearly 1 foot, or 0.28 meters.
But this is not all. There are over 300 such siliceous deposits around the world. If each one of them is only one-fourth the size of the Monterey, then there are enough dead diatoms to cover the earth uniformly to a depth of 21 meters, or 70 feet! So we now have a preflood world which contains 2,100 terrestrial animals per acre (none of which are human), a tropical rain forest everywhere, 20 meters of dead diatoms over the entire globe and 1 meter of dead coccoliths. Where is everyone going to live? And we are not through.

Too Many Crinoids [see picture at end of this post--grm]

The Mission Canyon formation in the northwestern United States is part of a truly remarkable deposit. It is largely made of the remains of dead crinoids, which are deep-sea creatures called sea lilies. Clark and Stearn report,

"Much of the massive limestone formation is composed of sand-sized particles of calcium carbonate, fragments of crinoid plates, and shells broken by the waves. Such a sedimentary rock qualifies for the name sandstone because it is composed of particles of sand size cemented together; because the term sandstone is commonly understood to refer to a quartz-rich rock, however, these limestone sandstones are better called calcarenites. The Madison sea must have been shallow, and the waves and currents strong, to break the shells and plates of the animals when they died. The sorting of the calcite grains and the cross-bedding that is common in this formation are additional evidence of waves and currents at work. Even in Mississippian rocks, where whole crinoids are rare fossils, and as a result, it is easy to underestimate the population of these animals during the Paleozoic era. Crinoidal limestones, such as the Mission Canyon-Livingstone unit, provide an estimate, even though it be of necessity a rough one, of their abundance in the clear shallow seas they loved. In the Canadian Rockies the Livingstone limestone was deposited to a thickness of 2,000 feet on the margin of the Cordilleran geosyncline, but it thins rapidly eastward to a thickness of about 1,000 feet in the Front Ranges and to about 500 feet in the Williston Basin. Even though its crinoidal content decreases eastward, it may be calculated to represent at least 10,000 cubic miles of broken crinoid plates. How many millions, billions, trillions of crinoids would be required to provide such a deposit? The number staggers the imagination."46

In just this one deposit, there are enough crinoids to cover every square inch of the earth to a depth of 1/4 inch. Where would the vertebrate animals (in the Karroo Beds mentioned earlier) live if the whole world were covered with crinoids? But this deposit is not the only crinoidal deposit. Rocks of the lower Mississippian age are largely composed of crinoidal calcarenites - translation: dead crinoids. Further north in Canada, the deposit of crinoidal limestones is called the Rundle, and it is called the Lisburne limestone in Alaska. Both of these beds contain vast quantities of dead crinoids. Farther south, the crinoidal limestone is called the Leadville Limestone in Colorado, the Redwall in Arizona, and the Chappell in Texas, the Burlington and Keokuk limestones in the Mid-Continent region. The Burlington alone contains another 719 cubic miles of dead crinoids.47 It is called the Edwardsville Formation in Indiana. This Mississippian crinoidal rock unit is called the Ft. Payne in Tennessee, Kentucky and Georgia. But this is not the extent of this crinoidal limestone.
In Australia there is a deposit of crinoidal limestones called the Namoi and Bingleburra Formations.48 In Libya near the Timenocaline Wells, there is a 6 foot bed of crinoidal limestone.49 White crinoidal limestones are found along the banks of the Zilim River in the south part of the Ural Mountains.50 Belgium boasts a crinoidal limestone that reaches 2,100 feet thick.51 Without further documentation, which could have been provided, these crinoidal limestones are found in Egypt, Central Asia, and China. A Mississippian crinoidal limestone even tops Mt. Everest! With crinoids all over the Northern Hemisphere, where did land animals live? Where did the tropical rain forest live? Where did the diatoms come from? Where did the coal come from?
When it is realized that almost all of the limestone deposits in the world are biologic in origin, a problem quickly arises. There are 6.42 x 10^22 grams of carbon in the limestones of the earth and only 3 x 10^17 grams of carbon in the biosphere of the earth. The flood must have buried 214,000 times more living matter in limestone alone than is currently on the earth.
There are far too many dead animals to have fit on the preflood earth as envisioned by the global flood advocates. The fossil record can not even begin to be considered the remains of one preflood biosphere. It would have been too crowded!

How boring. More trash from the undergraduate-degreed Morton as to why he won't take God at His word, from his poor-quality book which he can't sell to any great extent. Instead, he arrogantly thinks that his puny understanding of limited data trumps what God has revealed. By his "reasoning", we should likewise disbelieve the eyewitness accounts of the Resurrected Christ because "science" says it's impossible.

Christians should not fall for his long-winded bluffs, especially when they have long ago been answered by creationist scientists who are actually qualified in geology, unlike Morton.

E.g. the Morton cites the Karroo formation and extrapolates its contents for the whole world, probably parroting the atheist Schadewald who is even less well qualified in science than he is. But the Karroo is a basin into which fossils would be washed in a Flood. So its concentration is much larger than average.

Note that the 800 billion is just a guestimate by Broom, and Whitcomb and Morris were perfectly entitled to cite it as an example of a fossil graveyard. And it's not as much as Schadewald claimed. If they originally lived in an area only equal to present-day subequatorial Africa, i.e. in an area of 10 million square kilometers, this would imply a population density of 800 reptile individuals per hectare. But studies of present habitats over wide areas show that iguanid lizards can live at 889 animals per hectare, anoles up to 110,000, Manchuria island pit viper 10,000, Colorado rattlesnakes 1235.

For more information, see Geology and the young earth by a qualified geologist and true Bible-believer who directly answers Morton's trash, and The Karoo invertebrate non-problem (PDF).

As for coal, Morton ignores the extensive role of pre-Flood floating forest ecosystems comprising arboreal lycopods (club mosses) and the burial of peat that accumulated in the 1600 years of the antediluvian world. See Too much coal for a young earth?. In fact, coal deposits are far better explained by burial during a Flood rather than slow accumulation in a swamp--see Coal: memorial to the Flood.

Chalk: under cataclysmic Flood conditions, explosive blooms of tiny organisms like coccolithophores could produce the chalk beds in a short space of time -- see Can Flood geology explain thick chalk beds?

...where Snelling argues (quoting Woodmorappe) that large areas of the sea at the end of the flood somehow produced growths of microorganisms normally associated only with heavy outpourings of organic pollution - but without any explanation of what these microorganisms fed on, or how the expansion covered such a large area.

Translation: Morton won't take Socrates' word for what God says. Neither do most other Christians.

Socrates appeal to authority would have more credibility if more than a tiny minority of religiously-guided geologists disagree with Morton. It's true that long study of geology gives one more understanding of it. But Morton is a geologist. And Socrates is supposedly, a chemist.

E.g. the Morton cites the Karroo formation and extrapolates its contents for the whole world,
No one I know of does that; it's unnecessary. One can merely observe the density of the fossils, examine the extent of the formation, and show that for that limited formation alone, the density of larger animals would be too great for the earth to bear, much less Africa.

probably parroting the atheist Schadewald who is even less well qualified in science than he is.
Many geologists and paleontologists have looked at the data. They come up with the same conclusions.

Note that the 800 billion is just a guestimate by Broom, and Whitcomb and Morris were perfectly entitled to cite it as an example of a fossil graveyard. And it's not as much as Schadewald claimed. If they originally lived in an area only equal to present-day subequatorial Africa, i.e. in an area of 10 million square kilometers, this would imply a population density of 800 reptile individuals per hectare. But studies of present habitats over wide areas show that iguanid lizards can live at 889 animals per hectare, anoles up to 110,000, Manchuria island pit viper 10,000, Colorado rattlesnakes 1235.
The size of the animals in the Karroo formation vary from small to the size of a cow, with the average about fox-sized. Show me an environment where you can get 800 foxes per acre.

Under cataclysmic Flood conditions, explosive blooms of tiny organisms like coccolithophores could produce the chalk beds in a short space of time -- see Can Flood geology explain thick chalk beds?
Sounds like a testable assertion. What do you think the conditions were, that permitted kilometers-deep accumulations of microorganisms in a year?

I really want to hear that one.

People watching should note that Scotrates has no science to offer so he ridicules those without a Ph. d. What does this imply of how he thinks of you if you don't have a Ph.D.???


Christians should not fall for his long-winded bluffs, especially when they have long ago been answered by creationist scientists who are actually qualified in geology, unlike Morton.
Socrates, do you have any thing SCIENTIFIC to say? Is all you can do against this data is talk about qualifications? Even poor uneducated dirt farmers in the third world know that the sun rises and sets. do they need a degree to speak of it?

The interesting thing to me about this illogical argument on qualifications of creationist geologists , is that no one has placed $22 million dollars into their hands to invest in finding oil. I have had that much money under my control each year for finding oil. The investors decided that my geologic knowledge was sufficient for them to risk their money with me. Can any one say that about Snelling, Walker, Austin? The result of the investor's trust was that I ended up finding around 700 million barrels of oil.

E.g. the Morton cites the Karroo formation and extrapolates its contents for the whole world, probably parroting the atheist Schadewald who is even less well qualified in science than he is. But the Karroo is a basin into which fossils would be washed in a Flood. So its concentration is much larger than average.
You misunderstood, as usual. I merely took the 800 billion animals bigger than a fox (which Morrs and Whitcomb claim) and spread those 800 billion over the 38 billion acres to see how many animals per acre there would have been. It means a ludicrous preflood animal density if that number is correct. Of course, Whitcomb and Morris didn't do the slightest gut check on the numbers to see if they made any sense. And given that there are fossil animals all over the world, in addition to fossils found in the Karroo, the preflood animal density would have had to have been higher than that calculated by the Karroo numbers. Logic is something wonderful, Socrates, you should learn some (and maybe a bit of math as well).

Note that the 800 billion is just a guestimate by Broom, and Whitcomb and Morris were perfectly entitled to cite it as an example of a fossil graveyard. And it's not as much as Schadewald claimed.
Of course they were justified in citing that number. But they then turn around and show how sloppy their science is by not thinking through the implications. The world simply couldn't support 21 fox-sized animals per acred (not counting the billions of fossil animals found over the rest of the world. If you want to align yourself with this kind of sloppy thinking, far be it from me to dissuade you.

If they originally lived in an area only equal to present-day subequatorial Africa, i.e. in an area of 10 million square kilometers, this would imply a population density of 800 reptile individuals per hectare. But studies of present habitats over wide areas show that iguanid lizards can live at 889 animals per hectare, anoles up to 110,000, Manchuria island pit viper 10,000, Colorado rattlesnakes 1235.
This is laughable. Here you are spouting nonsense and sounding so authoritative. Here is what I know about snake densities:

"The brown tree snake is extremely abundant on Guam, with localized estimates sometimes reaching 20 or more snakes per acre of jungle. These population density estimates are among the highest snake densities ever recorded. " http://www.aphis.usda.gov/oa/pubs/bts.html

Since a hectare is 2.5 acres, this says that the highest snake density is around 50 snakes per hectare, not your ludicrous, laughable, lamentable 1235.

One might get those numbers if one counts the snakes in a five foot square breeding event and then extrapolates it to a hectare, but that is silliness.

Anoles are tiny animals no where near the size of a fox. Yes they live in the kind of density numbers you mention in some rain forests, but they are irrelevant to the Karroo issue because they are tiny. It would be like you saying that bacteria live in higher densities than 21 per acre therefore my argument is wrong. Anyone can see that claim is foolish.

For more information, see Geology and the young earth by a qualified geologist and true Bible-believer who directly answers Morton's trash, and The Karoo invertebrate non-problem (PDF).
I see aboslutly nothing in either of those sites to support the silly numbers you claim (without any documentation) in these two urls.

As for coal, Morton ignores the extensive role of pre-Flood floating forest ecosystems comprising arboreal lycopods (club mosses) and the burial of peat that accumulated in the 1600 years of the antediluvian world. See Too much coal for a young earth?. In fact, coal deposits are far better explained by burial during a Flood rather than slow accumulation in a swamp--see Coal: memorial to the Flood.
I have been waiting for you to raise this silly claim. Consider a global flood with floating mats of vegetation dropping their matter all over the ocean. Stand with me now on one of these mats. As you look around the horizon all you see is water. No land anywhere. The mat merely floats whereever the current takes it. There is nothing to prevent the mat from floating anywhere over the entire earth.

Come back now to the present time. What we observe is coal on the continents but NO coal anywhere in the deep ocean basins. Not one bedded coal bed has ever been found under current water depths greater than 600 feet. Why did vegetable mats ONLY drop their material over the present continents? This is a big mystery for that concept and one which utterly falsifies it. The mats should have been able to float anywhere over the surface of the earth in a global flood, not just over present water depths of 600 ft or less.

Now, there are 35 trillion short tons of coal on earth http://wwwdggs.dnr.state.ak.us/scan2...t/PDF85-20.PDF

Given that coal is 90% carbon and living plant matter is about 18% carbon, it means that there is a 5 fold increase in carbon density when it moves from plant matter to coal. How much plant matter would 35 trillion short tons equal? Enough to cover all the land to a depth of 1.18 meters or almost 4 feet of solid plant matter (no spaces). That is how much coal is on the earth. and in the global flood it had to have existed at one time prior to the flood. Get real Soc.

Chalk: under cataclysmic Flood conditions, explosive blooms of tiny organisms like coccolithophores could produce the chalk beds in a short space of time -- see Can Flood geology explain thick chalk beds?
Answer my already posted objection to this silly claim. I noted that one such bloom would deplete the ocean of calcium carbonate and thus the blooms can't go on and on because there is not enough calcium carbonate left to make any coccoliths.

The Barbarian:


The size of the animals in the Karroo formation vary from small to the size of a cow, with the average about fox-sized. Show me an environment where you can get 800 foxes per acre.
But foxes, being warm-blooded mammals, require a higher food intake than reptiles, and hence need to be more widespread. Monitor lizards vary by about the same amount as the karoo fossils - 800 of them per acre would do.

Note that all the animals Socrates mentioned are much lighter than foxes (or monitor lizards).

The indications are that at least some of the advanced therapsids were warm blooded.

Show me where you learned that using a so-called "average" in such a situation as this is appropriate.

The Barbarian:

But how many of the karroo fossils are advanced therapsids? And how many of those were the warm-blooded ones?

Since the karroo argument works equally well with large lizards rather than foxes, there's no reason to refer to animals which have a higher resource need.

The Karoo argument "works" if one accepts all the hidden assumptions, which some would prefer to ignore because it suits their agenda.

If someone has access to the following out-of-print book perhaps they will enlighten us with some quotes written by the acknowledged "field expert" on the subject of the Karoo, instead of depending on hearsay and informal comments and estimates:

"The distribution of the Karroo vertebrate fauna : with special reference to certain genera and the bearing of this distribution on the zoning of the Beaufort beds", by James William Kitching.
Publisher: Bernard Price Institute for Palaeontological Research, University of the Witwatersrand; ASIN: 0854944273 131 pages

BTW, the 800 billion estimate was arrived at as follows:

“Compared with any other fossil deposit in the world the Karroo must be regarded as phenomenally rich. Our fossil beds cover an area of about 200,000 square miles in almost any area of which fossils may be found. Some areas are rather poor; others are extremely rich. Great areas are covered by wind-blown dust, and vegetation; and as a rule it is only in water courses, and on slopes that fossils can be seen. I estimate that there are lying today exposed to view the fossil remains of five animals on average in every square mile. In some areas there are 100; in some none. For every fossil that is exposed to view there must be a 1,000 hidden by dust and talus. If there are the remains of 1,000 animals on the shale surface on an average in every square mile, there would be in the Karroo, if the wind-blown sand and dust could be removed, 200,000,000 fossil animals exposed to view. The fossiliferous beds are of great thickness. In some areas they must be 4,000-5,000 feet thick; in others perhaps only 2,000 feet.. It would be a very conservative estimate that would put the average thickness at 2,000 feet, and at every few inches we have another page of the book, and another series of fossils to be revealed. I thus estimate that in the whole Karroo formation there are preserved the fossil remains of at least 800,000,000,000 animals.”
Broom, R., The Mammal-like Reptiles of South Africa, H.F.G. Witherby, London, p. 309, 1932.

After reading Broom's comments, for which I much thank you because I had never actually seen the original report, I have no desire to disagree with Broom. I will accept his assumptions which then means that there are 800 x 10^9 animals in this one deposit. But there are 21 animals per acre over the entire earth--land and sea. If you restrict the land animals to just the land, then the number is actually higher--something like 73 or so. If anyone thinks the preflood world was populated that densly, and with 4 feet of solid plant material covering the land, and with 6 meters of chalk creatures, then I would ask how on earth is this possible. I know that the value for chalk is higher than I cited in my FFF passage. Today I went back and analysed some maps of European chalks. I figure that in Europe there are 2,272,500 cubic km of chalk. this means that there are around 6.29501385 m of chalk if spread all over the world. And this just from the European chalks.

Where in all this did the buffalo roam?


If someone has access to the following out-of-print book perhaps they will enlighten us with some quotes written by the acknowledged "field expert" on the subject of the Karoo, instead of depending on hearsay and informal comments and estimates:
I would agree that Whitcomb and Morris' estimate was hearsay. They didn't always give credit where credit was due. Broom would be the expert because he actually spent years studying the Karroo. He was famous for that work long before he became famous for his fossil man work.

Remarkable. And some say creationists are gullible.

I don't blame you for changing the subject.

BTW, don't thank me. I stole the quote from Woody's paper. He thinks Bloom's number was essentially a WAG (my words not his).

Oh, now I understand. When you wrote your post to which I replied and said:

You were referring to yourself. I get it. Sorry for the misunderstanding.

I was fairly sure that if I mentioned Woody too soon you would never have thanked me for the quote. Actually I never saw his article before I started searching today/yesterday for the source and methodology of the 800 billion estimate. Just lucky to find it I guess.

I still find it remarkable that a scientist like yourself would take Bloom's WAG seriously.

If anyone doesn't know what a WAG is ask an engineer. If someone tries to explain it here they might get banned, or at least have the posting edited.

It is Broom's WAG, not Bloom. As to Woody, I will learn from anyone as long as the facts are correct. I have nothing personal against Pecz.. er I mean Woody. I just think his facts are wrong most of the time. When he is correct and I am wrong, I will gladly learn from him.

And I thank you for finding that quotation. I really do. I think it is always useful to know where ideas come from. My hat is off to you, but we don't have a hats off circle so I wil give you this:
