What is "aegisuchus"

Aegisuchus is an extinct genus of giant, flat-headed crocodyliform within the family Aegyptosuchidae. It existed in what is now Morocco during the Cenomanian age of the Late Cretaceous Epoch. The type species Aegisuchus witmeri was named in 2012 by paleontologists Casey Holliday and Nicholas Gardner, who nicknamed it "Shieldcroc" for the shield-like shape of its skull. A. witmeri is known from a single partial skull including the braincase and skull roof.
