Explanation:
The Cenozoic era is the era that is by far the best studied and known by the scientists. The main reason for this is that this era is the most recent one, and it is actually the era we live in. Because it is the most recent era, the Cenozoic is abundant with lot of evidence of what has happened in it. The fossil records are very rich as the fossils didn't had that much time to totally decompose.

The oceanic crust is also in abundance, which is not the case with the other eras as the oceanic crust is constantly suducted.
