The lecturer disputes the origin of fossils found in the remains of Tyrannosaurus rex that lived seventy millions years ago. WyDp0

The lecturer disputes the origin of fossils found in the remains of Tyrannosaurus rex that lived seventy millions years ago. The lecturer asserts that the discovered fossils are not likely to be neither blood vessels, nor red blood cells. Moreover, he excludes the possibility that they are collagen matrix remains. First, the lecturer states that it is possible that those remains are colonies of bacteria that were living in bones. The author claims that the hollows in bones are traces of blood vessels. However, the lecturer contends that those colonies are not blood vessels, but they are indeed some organic material which represents moist residues of bacteria. Secondly, the lecturer argues that the microscopic examination results revealed that the spheres are peaces of reddish mineral instead of red blood cells. According to the lecturer those spheres were discovered in the remains of some primitive animals which do not have red blood cells. Thus, having those sphere in such animals makes us believe that the spheres are indeed not red blood cells. Finally, the lecturer excludes the possibility that collagen is the substance which is found after the test leg bone. The lecturer argues that no collagen can be detect after seventy thousand years after the death of animals. Therefore, since Tyrannosaurus lived more that seventy million years ago, it is most probably not collagen, but a traces of researcher's skin.
