The Paleocene, which is the first (oldest) part of the Cenozoic Era, as the Cretaceous was the last of the Mesozoic Era.
It really wasn't an era. An Era was a much longer period of time. It was called the "Jurassic Period".
It was part of the Mesozoic Era.
The oldest period in the Mesozoic Era is the Triassic period, lasting from about 251 to 201 million years ago. It followed the Permian mass extinction and saw the early diversification of dinosaurs, as well as the first appearance of mammals and birds.
The Paleozoic precedes the Mesozoic. And our current era, the Cenozoic, follows the Mesozoic.
There were three periods in the Mesozoic Era. The Triassic Period, the Jurassic period & the Cretaceous Period.
The 4 eras are Cenozoic era, the mesozoic era, the paleozoic era, and the precambrian era.
