Hierosaurus is a little-known genus of pelvic dinosaurs from the Ankylosauria group .
Discovery and naming
The fossil remains of Hierosaurus were found in the Niobrara Formation in the US state of Kansas in the 1900s . The only known species and thus type species is H. sternbergii . The finds are dated in the Upper Cretaceous (between early and middle Campanian ) to an age of around 83 to 76 million years.
Systematics
Due to similarities with Nodosaurus , Hierosaurus is sometimes included in the Ankylosauria group of the Nodosauridae . Other systematics such as M. Vickaryous (2004) see the fossils as too sparse for an exact classification and therefore list it as "Ankylosauria incertae sedis ".
