Caenagnathus collinsi

† Caenagnathus collinsi is the type species of the oviraptorosaurian genus Caenagnathus, from the Late Cretaceous Horseshoe Canyon Formation of Alberta, Canada. Named in honor of collector W.H. Collins, it is known from a lower jaw with distinctive features including a high, compressed beak profile. As a large omnivore, it likely fed on plant material, eggs, and small animals. Its mandibular anatomy has been central to debates over caenagnathid taxonomy and phylogeny.

Diet & Feeding

Omnivore

Caenagnathus collinsi had a varied diet that included both plants and animals. Omnivorous dinosaurs were versatile feeders, able to exploit multiple food sources, which gave them an advantage in changing environments.

Time Period

Cretaceous Late Mesozoic Era

Caenagnathus collinsi 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.
