Dinosaurs wiped out suddenly

 Most of the theory on why the dinosaurs have gone extinct have been based on fossil evidence found in the Americas. In fact, nearly all the fossils in the late cretaceous were from North America. Recently, a group of paleontologist have found more fossil evidence in Europe. This evidence suggests that the Dinosaurs had gone extinct in their prime time. This evidence also further supports the theory that dinosaurs had been wiped out by an asteroid impact.

This connects to what we have learned as it relates to evolution. It was through the extinction of the dinosaurs that mammals were able to gain dominance and rule the land, much like how the dinosaurs had done so 65 million years ago. By better understanding how the dinosaurs went extinct, it is easier to understand the conditions in which the mammals had to evolve in, leading to a potentially better understanding of how mammals evolved after the dinosaurs.

  1. How does the discovery of these fossils show that dinosaurs went extinct in their "prime time"?

  2. How does this particular piece of evidence support the asteroid theory?
