The author and the professor have a conflict of opinions about a fossil of Tyrannosaurus rex. The author states that the fossil contain remails of the animal's tissues, while the professor refutes this statement.
Firstly, the writer asserts that the small branching channels found in the bones may represent the hollows in which the blood vessels might have existed. However, the speaker refuted this opinion by claiming that these channels may not be blood vessels. As a matter of fact, bacteria living in bones will result in hollows which are similar to the blood vessel hollows. In addition, bacteria can produce organic materials when living in bones. This suggests that the channels might also be traces of bateria living in the animal's bones.
Secondly, the reading passage proposes that the spheres found in inner bones can probably be the remains of red blood cells, for they contain a chemical which is essential for transporting oxygen and some dark red centers which are similar to the red blood cell's size. By contrast, the listening material casts doubt on this statement by mentioning the fact that the spheres are also found in other animals in the same place, some of which do not contain red blood cells. As a result, the spheres are unlikely to be remains of red blood cells, but rather a kind of reddish mineral.
Thirdly, the article claims that collagen is found inside the animal's leg bone, supporting the statement that they are remains of the animal's bone tissue. On the contrary, the lecture believes that this statement does not hold water. As collagen have not been found in any animal remain older than one hundred thousand years, the collagen found in the animal's bone can impossibly represent Tyrannosaurus rex, which lives 70 million years ago. Instead, it may be from researchers handling the bone, as human skin also contain collagen.
