Sierraceratops is a type of horned dinosaur that lived during the Late Cretaceous period, around 72 million years ago. Its name means “Sierra horned face” because it was found in Sierra County, New Mexico.
This dinosaur is part of a family called Ceratopsidae, which includes many well-known horned dinosaurs. Sierraceratops belongs to a group known as chasmosaurines, which are known for their distinctive large frills and horns.
The first fossils of Sierraceratops were discovered in 1997 on a ranch owned by Ted Turner, the founder of CNN. A geologist named Gregory H. Mack found these dinosaur bones, which had been exposed by erosion. Later, a team from the New Mexico Museum of Natural History worked with the ranch manager to uncover more fossils. Initially, these bones were thought to belong to a different dinosaur called Torosaurus, but further studies showed that Sierraceratops was distinct.
Sierraceratops was a medium-sized dinosaur, recognized by its short, thick brow horns and a long cheek horn. Its neck frill had large openings that are characteristic of this dinosaur group. The fossils show that it had a mix of bones, including parts of its skull and vertebrae, with about 16% of its skeleton having been preserved.
Research has placed Sierraceratops closely related to other dinosaurs like Bravoceratops and Coahuilaceratops, indicating that several unique horned dinosaurs lived in the southwestern United States and Mexico during the Late Cretaceous.
In summary, Sierraceratops was a fascinating dinosaur known for its unique features and important place in the study of ceratopsians, helping us understand more about the diversity of dinosaurs that once roamed the earth.
