Lemurosaurus pricei

Lemurosaurus was a burnetiamorph, a kind of ancient pre-mammal.  At this stage, it was unlikely to have had fur.  Lemurosaurus is known from a couple of skulls from the late Permian (about 260 million years ago), South Africa.  Its name means 'ghost lizard' for its rather spooky appearance.  It had thickenings like a pair of horns over its eyes.  Its eyes were quite large, hinting possible nocturnality.  It had long-sharp canine teeth and was likely a hunter of small creatures.  It was about cat- to medium-dog-sized.
