  • T-rex Question

    http://www.msn.com/en-us/news/techno...D=ansmsnnews11

    This occurred to me while I was tormenting Rogue - which I realize doesn't narrow it down much.

    Anyway, serious question and no, I am not trying to start anything.

    How do they know these things weren't water dwelling? The modern animals I know of that resemble the walking structure live in and around water (with one exception, a bird that uses it's beak to help it climb). The dinosaurs like T-rex look like wading birds to me - I was just wondering why they are believed to have been land dwellers instead?

    probably because they are not found near fish or with fish in their bellies?

      Darn, and here I thought this was going to be a Marc Bolan question.


      When you say water dweller, what sort of bird exactly do you have in mind? Like flamingos? Cranes?

        Relevant to this, we've actually found Tyrannosaur bite marks on the skeletons of other animals, and they were land dwellers.

          But wouldn't that also be true of crocodiles that often prey on land dwelling animals?

          Okay, I admit I don't get how a T-rex could loom over the water waiting for something to wander too close but then again, I don't get how anything would let itself get close to one of those things.

            Yes, but I had ducks and geese more in mind. Something wading more shallow - simply because that's what it reminds me of.

              Yup. Generally things like hadrosaurs and Triceratops (which are terrestrial) made up most of their diet. But, much like many top level predators today, they weren't above scavenging, so it could vary. And if you want to see what the jaws of a huge dinosaur predator that was geared toward being a piscivore check out Spinosaurus, which lived in northern Africa not long before T rex came on the scene -- and was larger than a T rex[1].

              There are other details such as where (the type of deposits) their fossilized poop (coprolites), footprints and bones have been found in. Plus comparative morphology with other tyrannosauroids and other theopods. At












              1.

              I should add that I saw a lot of, shall we say, "imaginative" depictions of Spinosaurs out there.

              I'm always still in trouble again

                And the digested bones of the same types of animals they bit have been found in their coprolites (fossilized poop).

                  I probably should explain the bolded part a bit further.

                  All of the T rex fossils come from what is known as the Hell Creek Formation, which has been dated at being from the Late Cretaceous and found in sections of Montana, North Dakota, South Dakota, and Wyoming.




                  When T rex were alive the area was fluvial in nature -- a flat, forested floodplain.


                  ETA: Tarbosaurus which was T rex's close cousin from China that was nearly as big and lived around the same time also inhabited floodplains

                    All T-Rex fossil are found in uplands.

                    All the T-Rex tracks found are in terrestrial sediments. The bone, leg and foot structure is that of a land dweller. Actually the feet of land birds are close to the structure of T-Rex. Water birds have webbed feet. Sea dinosaurs mostly have webbed feet, or flippers. Coast dinosaurs have partial or full webbed feet.

                    The dinosaurs that were in the diet were land dwellers we have no evidence of T-Rex bit marks on the sea creatures. There were sea dinosaurs that were equivalent predators of T-Rex. One was crocodile relative with a T-Rex like head, and was larger than the T-Rex. Other crocs looked like crocs, and crocs are mainly land reptiles the hunt in the rivers and coastal waters. Another was sea dinosaur carnivore Tyrosaurus was a species of Mosasaur.) larger than the T Rex and very much adapted to the Ocean. If T-Rex wandered into the water it probably would be eaten.

                      Um, uplands or floodplains? Upland implies above the floodplain, to my understanding.

                      Thanks guys! I do appreciate the answers!

                        Although, Teal, there is some pretty good evidence that T-rex did live near the water and fished for food.

                            I include flood plain as the domain of upland animals whe contrasting the habitat of animals with marine, lakes, and river environments.
