Chasmosaurus russelli

† Chasmosaurus russelli is a species of Chasmosaurus from the Dinosaur Park Formation of Alberta, Canada, named in honour of palaeontologist Loris Russell. Distinguished from C. belli by differences in frill shape and horn proportions, it inhabited the same Campanian river delta ecosystems. A large quadrupedal herbivore, it likely lived in herds and used its frill in visual communication. It represents one of the later chasmosaurines of the Dinosaur Park assemblage.

Diet & Feeding

Herbivore

Chasmosaurus russelli 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

Chasmosaurus russelli 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.
