In Depth

       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.
