Quinkana is an extinct genus of mekosuchine crocodylians that lived in Australia from ~24 million years ago to ~40,000 years ago. By the Pleistocene Quinkana had become one of the top terrestrial predators of Australia, possessing long legs and ziphodont teeth (lateromedially compressed, recurved and serrated). Quinkana comes from the "Quinkans", a legendary folk from Aboriginal myths.

Species[edit]

The species within Quinkana include: the type species Q. fortirostrum from Queensland of the Pliocene and Pleistocene, Q. babarra from Queensland of the Early Pliocene, Q. timara from the Northern Territory of the Middle Miocene, and Q. meboldi from Queensland of the Late Oligocene.

Appearance[edit]

The older species (Q. meboldi and Q. timara) were small in size, about 3 metres (10 ft), compared to the large Plio-Pleistocene species which evolved. Quinkana fortirostrum has been estimated to have reached 6 metres (20 ft) in length,[1] making it at the time one of Australia's largest predators, second only to the giant monitor lizard, Megalania.

Closely related species[edit]

Quinkana is a genus within the subfamily Mekosuchinae. Other genera included in this family are: Australosuchus, Baru, Kambara, Mekosuchus, Pallimnarchus and Trilophosuchus.
