T Rex bone tissue

T Rex bone tissue Nrnn2
The reading and the listening both discuses the identification of the fossil remains of Tyrannosaurus rex (T. rex). The article states the three postulates to provide the shreds of evidence that tissue remails of 70-million-year old T. rex were discovered from the fossils of the leg bone, however, the lecture refutes all the three points and claims that these fossil findings are skeptical by presenting counter-arguments for each of the assertions. First and foremost, the passage begins by asserting that the presence of hollows indicates blood vessels' presence which is further confirmed by the discovery of a soft organic substance inside the leg bone of T- rex. . This claim is challenged by the lecture by pointing out that it could be anything else other than blood vessels and elaborates this by arguing that long after the animals died, bacteria colonized in the hollows. These bacterias left behind traces of soft organic residue and that is misunderstood with the organic contents of blood vessels. Next, the professor in the lecture rejects the second argument about dark red spheres by illustrating a couple of facts. First, If the spheres were red blood cells then all the primitive animals whose remains were found from the same place would have the red blood cells, whereas those primitive animals had not developed red blood cells. Second, these spheres were of different origins and were reddish probably because of some reddish minerals. These points refute the writer's implication that red spheres presented the identification of red blood cells as RBCs carry oxygen to tissues and, therefore, they are dark red colored too. Ultimately, the article wraps its arguments by declaring that a test revealed the presence of collagen fibers in T-rex which is a characteristic feature of bone tissue. The speaker in the listening rebuts this reason by insisting that collagen fiber would not have lasted for more than 100, 000 years whereas the T_rex fossil appeared to be 70-million years old. Hence, it couldn't be from T-rex leg bone and probably it had come from the skin tissue of a scientist who was experimenting on T-rex.
