Stomatosuchus inermis ("Weaponless mouth crocodile") was a 10 metre long stomatosuchid neosuchian from the Late Cretaceous (Cenomanian) of Egypt. Unlike most other crocodyliforms, it is difficult to determine exactly what S. inermis ate. Its flattened skull had a long, flat, lid-like snout, which was lined with small, conical teeth. The mandible may have been toothless and may have supported a pelican-like throat pouch.[1]

The only known specimen, a large skull, which was collected in German paleontologist Ernst Stromer's Egyptian expedition, was obliterated when the Munich Museum was destroyed during an Allied bombing raid in 1944.[2][3]
