''Kerberosaurus'' (meaning "Kerberos lizard") was a genus of saurolophine duckbill dinosaur from the late Maastrichtian-age Upper Cretaceous Tsagayan Formation of Blagoveshchensk, Amur Region, Russia (dated to 66 million years ago).〔Godefroit, P., Lauters, P., Van Itterbeeck, J., Bolotsky, Y. and Bolotsky, I.Y. (2011). "Recent advances on study of hadrosaurid dinosaurs in Heilongjiang (Amur) River area between China and Russia." ''Global Geology'', 2011(3).〕 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 new hadrosaurine. For the hadrosaurine, cranial material (holotype AENM 1/319, braincase, plus others) was distinctive enough to permit the naming of a new genus.
