In Depth Of all the pterosaurs Laopteryx probably has the least amount of fossil material attributed to it, only a rear portion of the skull. When Othniel Charles Marsh named it he thought that he was actually dealing with a prehistoric bird. This thinking held true until 1986 when John Ostrom found it to be … Read more
In Depth Analysis of the Lacusovagus fossils indicates that it is a member of the Chaoyangopteridae family of pterosaurs. This is significant as it up until the discovery of Lacusovagus, the members of this group were known only from Asia.

In Depth The Tatankaceratops type specimen was pieced together from partial remains before it was named in 2010, and soon after there were murmurings that it was actually a juvenile Triceratops. This stems down to a 2011 study by Nicholas R. Longrich which noted a mix of juvenile and adult characteristics in the skull. Since … Read more
In Depth Mirischia is a genus of compsognathid dinosaur that lived in what is now Brazil during the early Cretaceous. Mirischia means ‘wonderful ischia’, and this dinosaur acquired this name because the two ischia (bones of the pelvis) show an oval foramen (opening) in the left bone, and a notch in the same position on … Read more
In Depth Kulceratops is a very interesting genus of ceratopsian dinosaur as the holotype has been dated to coming from a fossil deposit Albian of the Early Cretaceous in age. This makes Kulceratops a candidate for being one of the first ceratopsian dinosaurs to appear. Unfortunately Kulceratops is only known from a partial maxilla (upper … Read more
In Depth Shuvosaurus was described from the discovery of a skull that had no teeth but a well-developed beak-like anterior portion. Because of this, Shuvosaurus was at the time considered to possibly be an ancient ancestor to the ornithomimosaurs, a group of dinosaurs that at the time of writing are only known from Cretaceous era … Read more
In Depth Platygonus is an extinct genus of peccary, a kind of artiodactyl mammal that is similar to a pig in physical appearance and ecological niche, yet is of a completely separate family. With larger Platygonus approaching one meter in length, they were quite a bit larger than modern peccaries. Platygonus may have been hunted … Read more
