In the reading passage, the author mentions several discoveries of T. rex's leg bone that are assumed to be remains of blood vessels, red blood cells, and collagen matrix. However, the lecturer keeps skeptical about these theories.
First, the author claims that the presence of a soft substance inside the channels of T. rex's bone seems to be the blood vessels of T. rex. The lecturer challenges that the organic substances are more likely to be the traces left by bacteria, which could have colonized in the hollow channels in the bones.
Second, the author suggests that the spheres would probably be the remains of red blood cells as the result of examination showed that they contained iron and dark red centers, essential substances of red blood cells. The lecturer contradicts this point, asserting that T. rex didn't have red blood cells when they were alive. Instead, the origins of these spheres merely belong to some reddish mineral.
Finally, the author states that the fibrous protein could be collagen matrix, a common material associated with bone tissue. The lecturer argues that the fossils are 70-million-year-old and that collagen can't last more than 100,000 years. Consequently, it is implausible to be T. rex's collagen. It is more likely to be the recent material left by human researches handling these bones.
