Centrosaurinae

† Centrosaurinae was a subfamily of ceratopsid dinosaurs from the Late Cretaceous of Laramidia (western North America). Characterized by short frills and prominent nasal horns — in contrast to the long brow horns of chasmosaurines — centrosaurines included iconic genera such as Centrosaurus, Styracosaurus, and Pachyrhinosaurus. These large herbivores often formed enormous gregarious herds documented by bone beds in Canada, browsing on low-growing vegetation with their parrot-like beaks and shearing dental batteries.

Diet & Feeding

Herbivore

Centrosaurinae 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

Centrosaurinae 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.
