'''Megalania''' is an extinct giant monitor lizard. It was one of the megafauna that roamed southern Australia, and appears to have become extinct around 40,000 years ago. It was once thought to belong to a distinct monotypic genus and called ''Megalania prisca,'' which means “ancient great butcher" (named in an attempt to illustrate the efficiency of its large, curved teeth). Its placement as a valid genus remains controversial, with many authors preferring sinking the genus into ''Varanus'' (Molnar, 2004), which encompasses all living monitor lizards. The first aboriginal settlers of Australia would certainly have encountered living Megalania.

Size of the ''Megalania''

Lack of enough fossil material has made it very hard to determine the exact dimensions of ''Megalania .'' (Molnar, 2004). Conservative estimates place the length of the largest individuals at a little over 7 meters (23 ft), with a maximum conservative weight of approximately 1940 kg (4,268 lbs [Molnar, 2004]). Average sized specimens would have been a leaner, but still impressive, 320 kg (704 lbs). ''Megalania'' was the largest land-dwelling lizard to have ever lived, and a fearsome predator as well as a scavenger. Judging from its size, ''Megalania'' would feed mostly on medium to large sized animals, including any of the giant marsupials like ''Diprotodon'' along with other reptiles, small mammals, and birds and their eggs and chicks. 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. Due to its size and similarities to the Komodo Dragon, a relationship between the two species has been suggested. In reality however, Megalania's closest living relative is the perentie, Australia's largest living lizard, not the Komodo Dragon.

Live ''Megalania''

There have been numerous reports and rumors of living ''Megalania'' in Australia, and occasionally New Guinea, as recently as the mid 1990s. Australian cryptozoologist Rex Gilroy has stated that ''Megalania'' is still alive today, and it is only a matter of time until one comes in. Aside from stories and eyewitness accounts, the only evidence that ''Megalania'' might still be alive today is plaster casts of possible ''Megalania'' footprints that Gilroy made in 1979.
