Mosasaurus hoffmannii

Mosasaurus hoffmanni was a famous animal that lived during the Late Cretaceous

The Late Cretaceous was the last epoch of the Cretaceous period and the Mesozoic era, spanning from the ending of the Albian age of the Early Cretaceous to the beginning of the Danian age of the Paleogene, 100.5 - 66 million years ago. It corresponds to the Upper Cretaceous series in stratigraphy. It is characterized by the diversification of theropods, ornithischians, crocodylomorphs and lepidosaurs. The Late Cretaceous is significant for the asteroid impact that wiped out the pterosaurs, non-avian dinosaurs and other prehistoric creatures at the end of the era, known as the K-Pg extinction event.


The Upper Cretaceous divided into six stages, all of them correspond to the ages of the same names in geochronology. From youger to oldest:


Late Cretaceous life[]

Many famous animals, such as Spinosaurus, Tyrannosaurus, Velociraptor and Triceratops lived during this epoch.
