Megaloolithus aureliensis

† Niobrarasaurus coleii was a nodosaurid ankylosaur from the Late Cretaceous Niobrara Formation of Kansas. A swimming ankylosaur recovered from marine deposits—likely its carcass floated offshore—it contributes to understanding ankylosaur biogeography and post-mortem transport.

Cretaceous Late Mesozoic Era

Megaloolithus aureliensis lived during the Cretaceous Late period of the Mesozoic Era, approximately 100.5 to 66.0 million years ago.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
