New ceratopsian dinosaurs from Utah

by Anonymous on Sep. 23rd, 2010

Two new ornately-horned dinosaurs unearthed recently in Utah are adding more knowledge to dinosaur science. They're also raising more questions about the ecology of the narrow landmass known as Laramidia where the two chasmosaurine dinosaurs lived about 75 million years ago. Kosmosceratops richardsoni and Utahceratops gettyi were both discovered in a remote area of the Grand Staircase-Escalante National Monument, a high desert region in south-central Utah. The two Late Cretaceous herbivores are related to Triceratops but had large, squared skull frills decked out with many unusual and ornate horns (up to 15 in Kosmoceratops' case) rather than just three like their well-known cousin. In this short video from the Utah Museum of Natural History, lead paleontologist Scott Samson (aka Dr. Scott on public television's popular Dinosaur Train) explains what some of those horns may have been used for, as well as the importance of the find.You can also read more about the discovery here.
