…was a very large (10m/32ft) stomatosuchid crocodilian from the late Cretaceous of Egypt. Unlike many other crocodyliforms it is largely unknown what exactly S. inermis ate. Its flattened skull had a long, lid-like snout which was filled with small conical teeth. Some theorize that the mandible might of been toothless and supported a pelican-like throat pouch.
Sadly the only known specimen (a large skull, collected by German paleontologist Ernst Stromer) was destroyed when the Munich Museum was bombed in 1944.
