He contends that this soft material is nothing but a residue of bacteria. However, the text affirms that this substance is in fact represent the remains of an actual blood vessels of T.rex.
Second, the professor explains that in the same location where T.rex fossils extracted scientists found iron in other animals like primitive animals who are not supposed to have any red blood cell at all. He added that the iron could be just be reddish minerals that came in contact with T.rex fossils. However, the text claims that the microscopic examination reveals presence of spheres that could be the remains of red blood cell of T.rex.
Finally, the professor asserts that collagen was never found in fossils older than 1000 years, this will directly contradict the fact that collagen has been found in a fossils that goes back to 70 million years.
