Albertaceratops nesmoi

†Albertaceratops nesmoi was a chasmosaurine ceratopsian from the Late Cretaceous (~77 Ma) of Alberta, Canada. A large quadrupedal herbivore bearing prominent brow horns and a parietal frill, it was named by Ryan in 2007. Found in the Oldman Formation, it helps document the evolutionary transition of horn and frill morphology in ceratopsians across time and geography.

Diet & Feeding

Herbivore

Albertaceratops nesmoi 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

Albertaceratops nesmoi 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.
