Ancient Animals | Quinkana

Quinkana is an extinct genus of mekosuchine crocodylians that lived in Australia from about 28 million to about 10,000 years ago. Most attributed specimens have been found in Queensland.

It is speculated to have been one of the top predators of Pleistocene Australia, along with megalania, the giant monitor lizard, and the modern saltwater crocodile.


The prehistoric mekosuchine crocodilian Quinkana differed considerably from the modern semi-aquatic crocodilians. Only known from Australia, Quinkana lived primary, perhaps even entirely, on land. At five to six meters long, the largest species of Quinkana, Quinkana fortirostrum, was one of the largest terrestrial predators in Australia during the last ice age.
