Stomatosuchus (type species S. inermis) is an extinct stomatosuchid neosuchian from the Late Cretaceous (Cenomanian) of Egypt that grew up to 10 metres (33 ft) long when it was alive. 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. The type, and only, specimen of S. inermis consists of a partial skull and two caudal vertebrae.
