About Eotrachodon
What it was like
Eotrachodon was an early duckbill, a plant eater with a broad beak and many grinding teeth. It had a large bump on its snout. Its skull and skeleton are fairly complete.
Its world
It lived about 86 to 84 million years ago, in the Late Cretaceous, in what is now Alabama. At the time, eastern North America was a separate land called Appalachia, split from the west by a sea. It shared that land with the duckbill Lophorhothon.
How it was found
Prieto-Márquez and colleagues named Eotrachodon in 2016. It suggests that duckbills first appeared in Appalachia.
