About Avaceratops
What it was like
Avaceratops was a small horned dinosaur. The best known skeleton is about 2.3 meters (8 feet) long, but it seems to be a young animal, so adults were larger. It had a short frill and a nose horn.
Its world
It lived in the Late Cretaceous, in what is now Montana. It comes from the Judith River Formation, where it shared the land with the tyrannosaurs Daspletosaurus and Gorgosaurus and the duckbill Corythosaurus.
How it was found
Dodson named Avaceratops in 1986. The type species is Avaceratops lammersi. Its name honors the wife of the man who found it.
