Ceratopsidae

† Ceratopsidae was a family of large-bodied, horned ceratopsian dinosaurs from the Late Cretaceous of Laramidia (western North America) and Asia. The family split into Centrosaurinae (prominent nasal horns, short frills) and Chasmosaurinae (prominent brow horns, long frills). Canada, particularly Alberta's Dinosaur Park Formation, has produced some of the most diverse and complete ceratopsid assemblages known. These social herbivores ranged from 4 to over 9 m long and weighed up to 13,000 kg.

Diet & Feeding

Herbivore

Ceratopsidae was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Cretaceous Late Mesozoic Era

Ceratopsidae 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.
