Essay about fossils related to animal tissues

Both the reading passage and the lecture discuss the issue of fossils related to animal tissues. The reading passage contradicts to the lecture.

Initially, the article outlines that the lots of tiny branching channels are found inside of the leg bone fossil, whilst the lecture argues it, stating that soft tissue is expected to be found in the channels are more likely to be left by bacteria.

Furthermore, the author mentions that spheres are found in inner bone and red blood cells can be remained and in reading passage, it’s mentions that the spheres have red centers. The professor departs from the idea, underscoring that there is no evidence show that creature at that time had red cells and the red centers should be something else.

Lastly, according to the reading passage it talks about that collagen is found on the leg bone. Collagen is a biochemical material, which might to be an association with bone tissue; whereas the lecture refutes it highlighting that collagen can’t live as long as 7 million year and it may be some recent material. For example, it may be from the hand skin of the researchers.

In conclusion the professor does not agree with the reading passage.
