Ceratopsia

ceratopsian

(Marsh 1890)

Ceratopsia or Ceratopia is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Asia and Europe, during the Cretaceous Period, although ancestral forms lived earlier, in the Late Jurassic of Asia. The earliest known ceratopsian, Yinlong downsi, lived between 161.2 and 155.7 million years ago. The last ceratopsian species, Triceratops prorsus, became extinct during the Cretaceous–Paleogene extinction event, 66 million years ago.

Leptoceratops: Beast of the Week

limb Canada Cretaceous Late Cretaceous Ceratopsia +2

Today we will be looking at the small ceratopsian dinosaur, Leptoceratops gracilis!Leptoceratops was a plant-eating ceratopsian dinosaur that lived in what is now Alberta, Canada, during the late Cretaceous period, between 68 and 66 million years ago. From beak to tail it measured about 6.5 feet (about 2m) and would have been able to walk on four or two limbs when alive. The genus name translates to "small horned face".

Pentaceratops: Beast of the Week

Mexico United States Cretaceous Late Cretaceous Ceratopsia +2

This week we will be checking out yet another awesome ceratopsian dinosaur. Enter Pentaceratops sternbergii! Pentaceratops was a plant-eating dinosaur that measured about twenty feet long from beak to tail. As a ceratopsian (horns, beaks, and frills) it was member of the chasmosaurine group, and was closely related to Chasmosaurus and Coahuilaceratops to name a few. It lived in what is now New Mexico, USA, during the late Cretaceous Period, between 76 and 73 million years ago. The genus name,
