The extinction of the dinosaurs at the end of the Cretaceous period is generally believed to have been caused by the Cretaceous Paleogene impact event which created the Chicxulub crater, demonstrating that impacts are a serious threat to life on Earth.

The chalk is part of the Upper Cretaceous System and the fossils it contains are marine in origin.

Saltasaurus (which means lizard from Salta ) is a genus of titanosaurid sauropod dinosaur of the Late Cretaceous Period.

The fossil record of Xenosauridae extends back to the end of the Late Cretaceous with the species Exostinus lancensis .

Dodson has proposed that Late Cretaceous ceratopsians may have knocked down angiosperm trees and then sheared off leaves and twigs.

Dicynodonts were long thought to have become extinct near the end of the Triassic, but there is evidence that they survived into the Cretaceous.

Other studies, including molecular clock studies, have estimated the origin of the primate branch to have been in the mid Cretaceous period, around 85 mya.

Their perceived decline in the early Cretaceous is most likely a bias in fossil sampling, as most fossils are known from Europe and North America.
