Kerberosaurus

Kerberosaurus (meaning "Kerberos lizard") is a genus of saurolophine duckbill dinosaur from the late Maastrichtian-aged (Upper Cretaceous) Tsagayan Formation of Blagoveshchensk, Amur Region, Russia (dated to 66 million years ago). It is based on bonebed material including skull remains indicating that it was related to Saurolophus and Prosaurolophus.

==History== In 1984, Yuri Bolotsky and the Amur Complex Integrated Research Institute discovered a large dinosaur bonebed at Blagoveschensk. Most of the remains were of Amurosaurus (a lambeosaurine hadrosaur), but some came from turtles, crocodilians, theropods, nodosaurids, and a saurolophine. The cranial material (holotype AENM 1/319, a braincase, and other skull bones) of the saurolophine was sufficiently distinctive to permit the naming of a new taxon, Kerberosaurus manakini, described twenty years later.
