herbivorous with some omnivory. Progura gallinacea (the giant malleefowl) was a larger relative of the extant malleefowl (Leipoa ocellata). Reptiles Varanus priscus (formerly Megalania prisca) (the megalania) was a giant carnivorous goanna that might have grown to as long as , and weighed up to (Molnar, 2004). Giant goannas and humans overlapped in time in Pleistocene Australia, but there is no evidence that they directly encountered each other. Wonambi naracoortensis was a non-venomous snake of in length. It was an ambush predator living at waterholes located in natural sun traps and killed its prey by constriction. Quinkana was a terrestrial crocodile that grew from to possibly in length. It had long legs positioned underneath its body, and chased down mammals, birds and other reptiles for food. Its teeth were blade-like for cutting rather than pointed for gripping, as with water-dwelling crocodiles. It belonged to the mekosuchine subfamily (all now extinct). It was discovered at the Bluff Downs in Queensland. Liasis dubudingala, lived during the Pliocene epoch, grew up to long, and is the largest Australian snake known. It hunted mammals, birds and reptiles in riparian woodlands. It is most similar to the extant olive python (Liasis olivacea). Meiolania was a genus of huge terrestrial cryptodire turtles measuring in length, with horned heads and spiked tails. Extinct megafauna contemporaneous with Aboriginal Australians Monsters and large animals in Dreamtime stories have been associated with extinct megafauna. The association was made at least as early as 1845, with colonists writing that Aboriginal people identified Diprotodon bones as belonging to bunyips, and Thomas Worsnop concluding that the fear of bunyip attacks at watering holes remembered a time when Diprotodon lived in marshes. In the early 1900s, John Walter Gregory outlined the Kadimakara (or Kuddimurka or Kadimerkera) story of the Diyari (similar stories being told by nearby peoples), which describes the deserts of Central Australia as having once been "fertile, well-watered plains" with giant gum trees, and almost solid cloud cover overhead. The trees created a roof of vegetation in which lived the strange monsters called Kadimakara—which sometimes came to the ground to eat. One time, the gum trees were destroyed, forcing the Kadimakara to remain on the ground, particularly Lake Eyre and Kalamurina, until they died. In times of drought and flood, the Diyari performed corroborees (including dances and blood sacrifices) at the bones of the Kadimakara to appease them and request that they
