Protosuchus haughtoni from the Lower Jurassic Stormberg series of southern Africa is closely similar to the contemporaneous P. richardsoni from the Moenave Formation of North America. The taxon is based on two well preserved braincases; the rest of the skull is described here, based on an exceptionally well preserved and virtually complete skull.
