| Their ornamented dome may have served as a communication system that was primarily visual within species, analogous to the crests, horns, and frills of ceratopsid dinosaurs. |
|
| The dino belongs to the chasmosaurine ceratopsid family, which are defined by elaborate frills on their skulls. |
|
| The specimen is the first Campanian-aged chasmosaurine ceratopsid found in Montana. |
|
| Similarly, the ceratopsid dinosaur Nedoceratops, which is known from a single specimen, possessed a small opening in its frill that suggests that it could be an intermediate growth stage between Triceratops and Torosaurus. |
|
| The samples included the claw of a meat-eating dinosaur, a few toe bones from a ceratopsid and a duck-billed hadrosaur, and rib fragments from an unknown species. |
|
| The dinosaur, a distant cousin of Triceratops called Xenoceratops foremostensis, is one of the oldest specimens known to date of the ceratopsid group. |
