The ancient crocodile species in Australia was able to run extremely fast on land 40,000 years ago

There were several species of crocodiles that lived in Australia during the Pleistocene epoch, which ended approximately 11,700 years ago.

One of these species, the extinct Quinkana, was a large and powerful crocodile that is believed to have been able to run on land.

Based on fossil evidence, scientists estimate that Quinkana could grow up to 6 meters (20 feet) in length, which is comparable in size to the largest living crocodile species today, the saltwater crocodile.

However, Quinkana had a different body shape than modern crocodiles, with shorter legs and a more muscular build that would have allowed it to move more efficiently on land.

While the exact speed that Quinkana could run on land is not known, studies suggest that it was likely capable of short bursts of high-speed running.

This would have allowed it to catch prey that lived both in water and on land, making it a formidable predator in its ecosystem.
