The reading and the lecture are both about a dinosaur fossil. The author of the reading presents three theoies about why the fossil contain actual tissues of the dinosaur. The lecturer disputes the claims made in the reading. According to the reading, soft substances found inside the bones may well represents the actual blood vessels of T. rex. The speific argument is challenged by the lecturer. He claims those substances has no relation to the blood vessel. Additionally, he points out that bacterias are responsible for making those substances Secondly, the author mentions that speheres which can be found in T. rex contain red blood cells. The lecturer, however, asserts that same spheres are found in other animals's fossils but they didn't conatain any blood cells. However, those spheres just contain red minarels. Finally, the lecturer mentions that. it is impossible that collagen can be found in the 700 years old fossil. Thus, collagen doesn't come from T. rex. It probably came from a researcher who touched it from some research purpose. This directly contradicts what the author indicates.
