About Geminiraptor
What it was like
Geminiraptor was a troodontid, a feathered theropod with large eyes. It is known from an upper jaw. The jaw bone is hollow and swollen, unlike that of any other troodontid.
Its world
It lived in the Early Cretaceous, in what is now Utah. It comes from the Cedar Mountain Formation. It is one of the oldest troodontids known from North America.
How it was found
Senter and colleagues named Geminiraptor in 2010. Its name refers to twin universities that worked together on it.
