Tristraguloolithus

† Tristraguloolithus is a Late Cretaceous ootaxon from Mexico, characterized by a distinctive eggshell microstructure combining features of different egg families. These trace fossils of dinosaurian nesting behavior expand the known ootaxon diversity of Cretaceous North America.

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.
