The passage asserts that Tyrannosaurus rex' s bones have tissues of blood vessels, red blood cells, and collagen matrix and provides three resons of support. The lecturer, on the contrary, repudiates this point ans says that these reasons are skeptical and rebuts all mentioned reasons by the passage.
First, the article claims that Tyrannosaurus rex has some channels inside led bone. The professsor debunks this idea by explaining that channels are not neccessarily remains of tissue. They are remains of colonized bacteria which have left, since they have left organic minerals.
Second, there aresome spheres in the bone which reveals that they are remains of blood cells, since those spheres have color and size of blood cells, according to the reading. The professor disavows this point by saying that these relics are identical properties of other animals in the same area which shows they are not red blood. He also states that these red spheres are remains of redish organic minerals.
Third, the author of the passage imparts that leg bone of Tyrannosaurus rex has collagen which is kind of material included in bone tissue. The lecturer casts doubt on this passae' claim by disapproving that collagen is not belong to Tyrannosaurus rex reasonin gthat they were from an earlier time. He avers that those collagen may have recent source like remins of human' skin whic is from researchers handled Tyrannosaurus rex's bones.
