New information on the holotype of “ Chasmosaurus ” russelli (Ornithischia: Ceratopsidae) necessitates the establishment of a new genus to receive the species

Canadian Journal of Earth Sciences
Although the holotype of Chasmosaurus russelli Sternberg, 1940, from the upper Dinosaur Park Formation of southern Alberta, shares features with other Chasmosaurus Lambe, 1914 specimens from Dinosaur Provincial Park as well as various chasmosaurine taxa from the southwest United States, it also possesses unique features of the premaxilla and frill ...

Exploring the ceratopsid growth record: A comprehensive osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) and its implications for growth and ontogeny

Cretaceous Research
Ceratopsids represent one of the most iconic groups of non-avian dinosaurs. These large quadrupedal ornithischians are well-known for their bizarre cranial ornamentations, which are distinctive among different ceratopsids. However, only very little data exist on ceratopsid osteohistology and growth rates.
