Tylosaurus capensisAlso known as Cape Mosasaur
Tylosaurus capensis prowled Late Cretaceous coastal waters as an imposing apex marine predator off southern Gondwana. Equipped with an elongated, cylindrical snout projecting beyond its front teeth, it used this robust bone ram to stun prey before biting with heavy, recurved jaws. A powerful hypocercal tail fin and paddle-shaped limbs drove this streamlined giant through continental shelf seas with explosive hunting bursts.
