Answer 1

The crisis that drastically reduced the diversity of dinosaurs and other reptiles occurred at the end of the Mesozoic era.

Explanation:

The mass extinction that caused the abrupt end of the dinosaurs and many other reptiles took place at the end of the Mesozoic era, specifically during the Cretaceous-Paleogene (K-Pg) extinction event, about 60 million years ago. This event is widely believed to have been triggered by a comet or meteorite impact, leading to dramatic environmental changes and the extinction of many species.
