TPO 24 integrated a bone of Trex revealed that there were blood vessels spheres that showed the remaining of red blood cells and collagen in their bodies

The article asserts that scholars have found interesting new discoveries about the ancient animals by breaking a T.rex's leg bone. Nevertheless, the professor not only casts doubt on the presumptions made by the author but also refutes all the essay's claims by three persuasive explanations. In the following, these justifications, used to shed light on this controversial issue, will be defined.

First of all, the reading claims that small branching channels inside the bones are hollows made by blood vessels. The educator completely overthrows this opinion, and insists that this soft, flexible tissue cannot be blood vessel; it is something else. He believes that as bacterias colonize inside hollows and live behind organic material, these empty places might be the residue of their colonies which were pleasantly moist enough for the bacterias.

Secondly, the passage declares that by examining the inner bone, researchers have concluded that spherical microscopic materials are the remainings of red blood cells. The teacher, on the other hand, reminds that these spheres are pretty identical among many animals. Therefore, as some primitive creatures did not have blood vessels, these spheres cannot represent red blood cells. They may have a whole different origin; may be a redish mineral.

Tertiary, the essay upholds that a test on the leg bone revealed that those animals had collagen. The lecturer, however, oposes this justification, mainly because he endorses that this material cannot remain for more than one hundred years, so the material which was found in a 70-million-year-old bone is unlikely. The professor thinks that this collagen is maybe the remaining of the researchers' skin who were handling the bone.
