Avaceratops lammersi

† Avaceratops lammersi was a Late Cretaceous ceratopsid from the Judith River Formation of Montana, described in 1986 by Peter Dodson. This herbivore is known from a partial skull and postcranial material representing a subadult individual. It possessed a relatively small frill and may represent the juvenile form of a larger centrosaurine or chasmosaurine ceratopsid.

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.
