Rhinorex is a genus of saurolophine hadrosaur that lived in the USA during the late Cretaceous. Rhinorex can be further identified as a kritosaurine due to the development of the bones on the snout which would have formed a bony display structure in life. However, Rhinorex is also noted as being very similar to Gryposaurus, which lived in a near identical location at the same time as Rhinorex, which has fuelled speculation that Rhinorex may actually be synonymous with Gryposaurus.
