Rabidosaurus is an extinct genus of dicynodont of the family Kannemeyeriidae. It was a fairly big dicynodont with which seems to have had a hump on the back of its head and a pointy horn on its snout which seems to have been probably used to ram each other like battling rams to fight for mates or for defense. Like all dicynodonts, it had two protruding teeth growing from its uppepr jaw and a short tail. A few sparse remains of this creature have been somewhere in Antarctica. Not very much is known about this creature.
