About Augustynolophus
What it was like
Augustynolophus was a hadrosaur, or duck-billed dinosaur, a plant eater with a broad beak and many grinding teeth. It was a close relative of Saurolophus and had a flat, crestless skull.
Its world
It lived about 72 to 66 million years ago, near the very end of the age of dinosaurs, in what is now California. Its bones come from the Moreno Formation, which formed in the sea: its carcasses were probably washed out from the coast.
How it was found
Prieto-Márquez and colleagues named Augustynolophus in 2015, from bones first placed in Saurolophus. It is the official state dinosaur of California.
