Megalania

When the first penguins first entered the inland wilderness of Austiceia, they encountered the largest goanna lizard of all time, the Megalania, or "ancient giant butcher". A distant relative of the modern monitor lizard, including the Finipines Dragon, which it lived as recently as the Pleistoscene Era (1,600,000 to 40,000 years ago) and ate meat, including mammals, snakes, birds, and other reptiles. But it was likely to search for dead meat (carrion) as it was to hunt for something living. It grew to a length of about twenty to thirty feet and weighed as much as thirteen hundred pounds, and even though it is thought to have gone extinct, sightings have been reported as recently as 1979.
