Ancient Rock Art Shows Tasmanian Tigers Lived 2,000 Years Longer

Archaeologists just discovered something remarkable hidden in the ancient rock art of northern Australia: proof that Tasmanian tigers may have walked the mainland 2,000 years longer than we believed.

A research team documented 14 new rock paintings of the thylacine (the scientific name for Tasmanian tigers) and two images of Tasmanian devils in Arnhem Land. The region, governed by Aboriginal communities with about 16,000 residents, has preserved much of its natural environment and cultural heritage.

Scientists previously thought Tasmanian tigers disappeared from mainland Australia around 3,000 years ago. The last known tiger died in a Tasmanian zoo in 1936, marking the species' complete extinction.

But these newly found paintings tell a different story. Some images were created using kaolin, a white clay pigment that doesn't last as long as other colors like red ocher. This means the artwork is relatively recent in archaeological terms.

"The artists who made the more recent paintings may have seen actual living thylacines," said Paul Taçon, a professor of rock art research at Griffith University. The paintings could be less than 1,000 years old, suggesting these striped marsupials survived in northern regions far longer than anyone realized.

The rock art shows incredible detail. One Tasmanian devil painting stretches 2 feet long with a slightly open mouth revealing sharp, pointed teeth. The tiger images depict dog-like animals with stripes, rounded ears, and long muzzles, with the longest measuring nearly 5 feet.

Not all the paintings show stripes, indicating that ancient artists sometimes chose to leave them out. Some images have other animals, like eel-tail catfish, painted over them, showing how the rock surfaces were used across different time periods.

The Ripple Effect

Before this discovery, researchers had verified about 150 rock art images of Tasmanian tigers and just 23 of Tasmanian devils across mainland Australia. The difference suggests tigers held greater cultural importance for Aboriginal communities.

The team is now working directly with Aboriginal groups to understand what these animals meant to their ancestors. Joey Nganjmirra, a co-author from the Djalama Aboriginal group, is helping connect the dots between ancient artwork and living cultural memory.

This research does more than push back extinction dates. It validates Indigenous knowledge systems that have preserved these stories for generations, showing that Aboriginal oral histories and artistic traditions contain valuable scientific information.

The discovery reminds us that there's still so much to learn from listening to and working alongside Indigenous communities who have been the original stewards of these lands for tens of thousands of years.
