It is the latest of three geological eras of the Phanerozoic Eon, preceded by the Mesozoic and Paleozoic. The Cenozoic started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body ...
A third factor which played a role in the Mesozoic-Cenozoic radiation was the K-Pg extinction, which marked the end of the dinosaurs and, surprisingly, resulted in a massive increase in biodiversity of terrestrial tetrapods, which can almost entirely be attributed to the radiation of mammals. There are multiple things which could have caused ...

Areas of Cenozoic North America that were covered by seawater tended to be areas near the modern coasts. [135] The Cannonball Sea near Minot, North Dakota was the last of the North American interior.

It lasted all through the time of the non-avian dinosaurs during the Mesozoic Era, and ended 33.9 million years ago in the middle of the Cenozoic Era (the current Era). This greenhouse period lasted 226.1 million years. The hottest part of the last greenhouse earth was the Late Paleocene - Early Eocene.
