Name: Cedarpelta bilbeyhallorum
Name Meaning: Bilbey and Hall’s Cedar Mountain Shield
First Described: 2001

Classification: Dinosauria, Ornithischia, Genasauria, Thyreophora, Eurypoda, Ankylosauria, Ankylosauridae
Cedarpelta is an early derived Ankylosaurid known from the Ruby Ranch Member of the Cedar Mountain Formation, living about 116 to 109 million years ago, sometime between the Aptian and Albian ages of the Early Cretaceous. It is known from an articulated skull lacking the snout and mandibles, as well as isolated bones. It was probably a large Ankylosaurid, about 7 meters long, though it may have been only 5 meters long. It showed a mixture of early derived and later derived Ankylosaurian traits, showing itself as a stepping stone in the evolution of Ankylosaurids. The skulls did not show fused head tiles, indicating that the development of these animals went differently than previously believed - since the known fossils aren’t of juveniles; it may indicate that the fusing of the skulls happened in a layer between the scales and skull roof itself. It also had a long, narrow snout, and similar teeth to animals such as Chuanqilong and Liaoningosaurus.
