Triceratops is a well known example. They were one of the most successful groups of herbivores of their time. Chasmosaurines appeared in the early Campanian , and became extinct, along with all other non bird avian dinosaurs, during the Cretaceous Paleogene extinction event . Broadly, the most distinguishing features of chasmosaurinae are prominent brow horns and long frills lacking long spines centrosaurines generally had short brow horns and relatively shorter frills, and often had long spines projecting from their frills. Chasmosaurines are currently known definitively from rocks in western Canada, the western United States, and northern Mexico.

It contains two species Edmontosaurus regalis and Edmontosaurus annectens . Fossil s of E. regalis have been found in rocks of western North America that date from the late Campanian Stage stratigraphy stage of the Cretaceous Geologic time scale Terminology Period 73 million years ago, while those of E. annectens were found in the same geographic region but in rocks dated to the end of the Maastrichtian stage of the Cretaceous, 65.5 million years ago. E. annectens was one of the last non bird avian dinosaurs, and lived alongside Triceratops horridus and Tyrannosaurus rex shortly before the Cretaceous Paleogene extinction event . Edmontosaurus included some of the largest hadrosaurid species, measuring up to convert 13 m ft sp us long and weighing around convert 4.0 MT ST . Several well preserved specimens are known that include not only bones, but in some cases extensive skin impressions and possible gut contents.
