Rhinorex was a recently discovered species of hadrosaur with a very distinctive snout.

It is likely a close relative of Gryposaurus, and indeed some have suggested that it falls within the genus Gryposaurus, as the phylogenetic analysis indicates.[1]

It is found in a very similar time and place as Gryposaurus monumentensis and Gryposaurus sp. This would challenge the idea of provincialism in Late Cretaceous Laramidian faunas. It may be that Rhinorex lived in more coastal environments than Gryposaurus.[1] Theholotype specimen BYU 13258 is composed of a partial but mostly articulated skeleton, which includes the skull, the vertebral column and a partial pelvis.


The type and only valid species known is Rhinorex condrupus. The specific name is derived from the Latin word "condo" which means "bury" and refers to the specimen being buried in rock and the Latin word "rupes" which means "cliffs" and is a reference to the fossil being discovered in the Book Cliffs of Utah.
