酷東西

趣味知識

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

發現: The first fossils of Nevadadromeus were found near Valley of Fire in Nevada in 2008. Scientists Bonde, Hall, Krumenacker, and Varricchio named it in 2022, honoring geologist James G. Schmitt.1
仍有爭議: Scientists are not sure whether Nevadadromeus was more closely related to thescelosaurines or orodromines, because its fossils show features of both groups.1
