Quinkana was a type of ancient crocodile that lived mostly on land. It is now extinct, meaning it no longer exists. These amazing creatures lived in Australia a very long time ago. They were quite large, growing up to 7 meters (about 23 feet) long. That's longer than a typical car!
Quinkana lived from about 24 million years ago until about 40,000 years ago. This means they were around for a huge stretch of time, through different periods of Earth's history.

What Was Quinkana?
Quinkana was a genus of crocodile. A genus is a group of very similar animals. Scientists have found fossils of different Quinkana species. These species include Q. fortirostrum, Q. babarra, Q. timara, and Q. meboldi. Each one was a bit different but belonged to the same Quinkana family.
Unlike modern crocodiles that spend most of their time in water, Quinkana was a "land crocodile." This means it was adapted to live and hunt on dry land. Its legs were likely stronger and more upright than those of today's crocodiles. This helped it move around on land more easily.
Unique Teeth of Quinkana
One of the most interesting things about Quinkana was its teeth. Most crocodiles have cone-shaped teeth, good for grabbing and holding prey. But Quinkana had teeth that were flattened and blade-like. They were also serrated, meaning they had jagged edges like a steak knife.
These special teeth suggest that Quinkana was a very effective predator. It could likely slice through the flesh of its prey. This is a bit like the teeth of a meat-eating dinosaur, not a typical crocodile.
Where Did Quinkana Live?
Quinkana lived only in Australia. Australia was home to many unique and large animals in prehistoric times. This ancient land crocodile was a top predator in its environment. It roamed the forests and grasslands of ancient Australia.
Fossils of Quinkana have been found in different parts of Australia. This shows that they were spread across the continent. They lived alongside other fascinating creatures of the time.
What Did Quinkana Eat?
With its large size and special teeth, Quinkana was an apex predator. This means it was at the top of the food chain. It likely hunted large animals that lived in Australia during its time. These could have included giant kangaroos, flightless birds, and other large marsupials.
Its powerful jaws and sharp, blade-like teeth would have made it a fearsome hunter. It probably ambushed its prey, just like modern crocodiles do. But instead of waiting by the water, it would have hidden in the dense vegetation on land.
When Did Quinkana Live?
Quinkana existed for a very long time. Its history spans from the Late Oligocene epoch to the Pleistocene epoch.
- The Oligocene epoch was from about 33.9 to 23 million years ago.
- The Miocene epoch was from about 23 to 5.3 million years ago.
- The Pliocene epoch was from about 5.3 to 2.6 million years ago.
- The Pleistocene epoch was from about 2.6 million to 11,700 years ago.
Quinkana disappeared about 40,000 years ago. This was around the time when humans first arrived in Australia. Scientists are still studying why these large land crocodiles became extinct. It could have been due to climate change, changes in their habitat, or the arrival of new predators, including humans.
