What can fossils of teeth tell us about extinct animals?.

Sagot :

Answer:

To understand what extinct animals, such as dinosaurs, ate, we can compare their tooth types to the range of tooth types that we see with modern animals such as these carnivorous and omnivorous animals. ... These kinds of clues tell us that this animal was a meat eating animal. This fossil is the jaw of a Hadrosaur.

Explanation:

Teeth from more recent fossils reveal more because they have more isotopes preserved in them. For example, the nitrogen in the teeth of Neanderthals can reveal whether the protein they ate came from plants or animals.

An animal's teeth is literally shaped by its food. That's according to new research from the Department of Geology at the University of Leicester, published in the Royal Society journal Interface. Research shows that the roughness of tooth surfaces can reveal what an animal has been eating.
