  • Feathered dinosaur tail preserved in amber.

    'Beautiful' dinosaur tail found preserved in amber
    By Paul Rincon Science editor, BBC News website



    "We can be sure of the source because the vertebrae are not fused into a rod or pygostyle as in modern birds and their closest relatives," he explained.

    "Instead, the tail is long and flexible, with keels of feathers running down each side."

    Dr McKellar said there are signs the dinosaur still contained fluids when it was incorporated into the tree resin that eventually formed the amber. This indicates that it could even have become trapped in the sticky substance while it was still alive.

    Co-author Prof Mike Benton, from the University of Bristol, added: "It's amazing to see all the details of a dinosaur tail - the bones, flesh, skin, and feathers - and to imagine how this little fellow got his tail caught in the resin, and then presumably died because he could not wrestle free."

    Examination of the chemistry of the tail where it was exposed at the surface of the amber even shows up traces of ferrous iron, a relic of the blood that was once in the sample.

    The findings also shed light on how feathers were arranged on these dinosaurs, because 3D features are often lost due to the compression that occurs when corpses become fossils in sedimentary rocks.

    The feathers lack the well-developed central shaft - a rachis - known from modern birds. Their structure suggests that the two finest tiers of branching in modern feathers, known as barbs and barbules, arose before the rachis formed.

      Cool discovery but that 160 myo find is from a 3 year old story.

      I'm always still in trouble again

          Old news. I think I covered it a couple years back in one of Jorge's threads.

                    It proves evolution is fake and that the world is flat.

                    Also the cow did not jump over the moon. That was faked by NASA

                      The moon-jump rhyme is a clear reference to ANE cow-worship. Therefore, the moon-landing myth is evidently also a reference to some Ancient Near Eastern moon-worship myth or ritual.

                        On a serious note, do you ''believe'' that biological evolution happened and is still happenning today?

                        I am asking because from my personal experience most Christians (especially Evangelicals) don't.

                        The obvious exception here being Rogue06.

                          I am not sure. To me it doesn't matter.

                            Fair enough.

                              I know I certainly believe in biological evolution. But then, I'm an admitted heretic.
                              "When the Western world accepted Christianity, Caesar conquered; and the received text of Western theology was edited by his lawyers…. The brief Galilean vision of humility flickered throughout the ages, uncertainly…. But the deeper idolatry, of the fashioning of God in the image of the Egyptian, Persian, and Roman imperial rulers, was retained. The Church gave unto God the attributes which belonged exclusively to Caesar."

                              — Alfred North Whitehead
