We describe and re−evaluate the systematics of specimens from the Maastrichtian Moreno Formation of California (west− ern USA) as a new species of Saurolophus, the only known genus of hadrosaurid dinosaur widespread in Asia and North America. Recognition of this new species adds substantially to the record of the taxonomic diversity of these animals west of the Rocky Mountains. The new species, Saurolophus morrisi, is diagnosed by the possession of a postorbital having or− namentation in form of wide oblique groove on jugal process. Placement of this new species in Saurolophus considerably expands the distribution of this genus, although this referral is arbitrary since phylogenetic analysis places the new species outside of the clade formed by Saurolophus osborni and Saurolophus angustirostris. However, recognition of a new, en− demic Californian hadrosaurid, especially one so closely related to both Asian and North American species, may have im− plications for future studies of both the internal biogeography of Western North America, and the history of exchange with Asia.
