Cretaceous Period In Geological Time Scale In Archaeology Anthroholic Dive into the cretaceous period, the final chapter of dinosaur dominance. discover new species, changing landscapes, and the road to extinction. It is the third and final period of the mesozoic era, as well as the longest. at around 77.1 million years, it is the ninth and longest geological period of the entire phanerozoic. the name is derived from the latin creta, ' chalk ', which is abundant in deposits from the latter half of the period.
Cretaceous Period Cretaceous period, in geologic time, the last of the three periods of the mesozoic era. it began 145 million years ago and ended 66 million years ago and featured the extinction of the dinosaurs at the end of the period. The cretaceous is usually noted for being the last portion of the "age of dinosaurs", but that does not mean that new kinds of dinosaurs did not appear then. it is during the cretaceous that the first ceratopsian and pachycepalosaurid dinosaurs appeared. The cretaceous period lasted for nearly 80 million years. discover what the climate was like in this geological period, where the continents were and what animals and plants lived on them. find out how an asteroid ended the age of dinosaurs. Explore the cretaceous period in "the age of the dinosaurs." discover iconic dinosaurs, dramatic events, and the rise of early mammals in this fascinating era.

Cretaceous dinosaurs roamed the earth like ancient titans, during a period that spanned approximately 79 million years, from 145 to 66 million years ago. they were the rulers of their era, experiencing significant environmental shifts. During the cretaceous, the allosaurs of the jurassic had become extinct with their relatives, carcharodontosaurids, taking over the southern hemisphere. however a new group of powerful super predator had emerged in the north and began to dominate; the tyrannosaurs. The carnivore tyrannosaurus rex dominated the late cretaceous in the north while monstrous meat eaters like spinosaurus, which had a huge sail like fin on its back, thrived in the south. The cretaceous period, spanning from 145 to 66 million years ago, was a time of extreme warmth and dramatic climate shifts. during this era, dinosaurs roamed the earth, and the world looked very different from what we know today.
