Prolacerta is a genus of archosauromorph from the lower Triassic of South Africa and Antarctica. The only known species is Prolacerta broomi. Prolacerta was a small and slender reptile, with a rather long neck, low skull, and serrated teeth. It would have resembled a modern monitor lizard at a quick glance, though this is an example of convergent evolution as opposed to close affinities.
