About Galeamopus
What it was like
Galeamopus was a long-necked plant eater, a relative of Diplodocus, with a long whip-like tail. It is known from several skeletons, including a very well preserved skull.
Its world
It lived in the Late Jurassic in what is now Wyoming and Colorado in the United States. Its bones come from the Morrison Formation, where it shared the land with Diplodocus, Brontosaurus, Stegosaurus and the hunter Allosaurus.
How it was found
Tschopp and colleagues named Galeamopus in 2015, for bones that had long been thought to belong to Diplodocus. Six finds are known.
