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. They seem to have disappeared sometime after 50,000 years ago. The first aboriginal settlers of Australia would have encountered them. Megalania is the largest terrestrial lizard known to have existed. Judging from its size, it would have fed mostly upon medium to large sized animals, including any of the giant marsupials like Diprotodon, its' main apex predator rival Thylacoleo and Procoptodon along with other reptiles like Quinkana, Meiolania and Wonambi and small mammals, as well as birds like Bullockornis and Genyornis and their eggs and chicks and even early man. It had heavily built limbs and body and a large skull complete with a small crest in between the eyes, and a jaw full of serrated blade-like teeth. Along with other varanid lizards, such as the Komodo dragon and the Lace monitor, Megalania belongs to the proposed clade Toxicofera, which contains all known reptile clades possessing toxin-secreting oral glands, as well as their close, non-venomous relatives, including Iguania, Anguimorpha, and Serpentes. Being a member of Anguimorpha, Megalania may have been venomous and if so, would be the largest venomous vertebrate known.
