Rhinorex

Rhinorex's fossil was first dug up in the 1990s, but it sat in storage for years because scientists were more interested in its well-preserved skin impressions than its bones.1

Unlike many other duck-billed dinosaurs, Rhinorex did not have a crest on top of its head. Instead, it had a huge, bony nose that gave it a very unique face.1

Rhinorex lived in an estuary, a swampy area where a river meets the sea, about 50 miles from the coast. This is different from its relative Gryposaurus, which lived further inland.1

Scientists are not sure why Rhinorex had such a big nose. It might have been used to attract mates, to recognize other members of its species, or as a base for a strong, plant-smashing beak.1

Rhinorex is the only complete hadrosaur fossil ever found in the Neslen Formation, making it a very important discovery for understanding Utah's ancient environments.1

The name Rhinorex condrupus means 'king nose' and 'pig-like' in Latin, a funny combination that matches its pig-like snout.12
