Fun facts

Nevadadromeus is the first non-bird dinosaur ever named from Nevada.1

Its name means 'Nevada runner' because it was built for speed.1

It lived about 100 to 94 million years ago during the Cretaceous Period.2

The fossils were found in the Willow Tank Formation, which was once a river floodplain.1 2

Nevadadromeus had a deep notch between the two bumps on its thigh bone, which helped scientists identify it as a new species.2

It is the oldest known member of its group (thescelosaurines) from North America.1
