The family, a group of carnivorous and frugivorous lizards, includes the extinct Megalania (the largest known lizard), the Komodo dragon (the largest living lizard), and the crocodile monitor. The Varanidae contain the living genus "Varanus" and a number of extinct taxa. Their closest living relatives are the anguid and helodermatid lizards. Megalania ("Megalania prisca" or "Varanus priscus") is an extinct giant goanna or monitor lizard. They were part of a megafaunal assemblage that inhabited southern Australia during the Pleistocene. The youngest fossil remains date to around 50,000 years ago. The first aboriginal settlers of Australia might have encountered them.
