Researchers and Traditional Owners have documented new Tasmanian tiger rock art in Arnhem Land, potentially reshaping understanding of mainland extinctions.
The Tasmanian tiger is often remembered as one of the world’s most famous extinct animals. Known formally as the thylacine, the striped marsupial once roamed across Australia before disappearing from the mainland and eventually vanishing entirely in the twentieth century. Now, a remarkable discovery in northern Australia is providing new insight into the animal’s history while highlighting the value of Indigenous knowledge and cultural heritage.
A Griffith University study conducted in partnership with Traditional Owners has documented 14 previously unrecorded thylacine images and two Tasmanian devil images at rock art sites across northwest Arnhem Land. Some of the artworks may be less than 1,000 years old, raising intriguing questions about when these species disappeared from mainland Australia. The findings place renewed attention on Tasmanian tiger rock art in Arnhem Land as an important source of both cultural and scientific knowledge.
For decades, scientists have generally believed that thylacines and Tasmanian devils disappeared from mainland Australia around 3,000 years ago. Researchers have suggested that environmental changes and the arrival of dingoes may have contributed to their decline. However, the newly documented rock art hints that at least some populations may have survived longer in remote parts of northern Australia than previously thought.
Rock art has long served as a visual record of Australia’s environmental history. Across Arnhem Land, thousands of paintings document animals, people, cultural practices, and landscapes spanning countless generations. These artworks provide researchers with rare insights into past ecosystems while preserving stories and knowledge that remain important to Indigenous communities today.
The newly documented Tasmanian tiger rock art in Arnhem Land depicts the distinctive striped bodies and elongated features associated with thylacines. Researchers were also surprised to identify two images believed to represent Tasmanian devils, another species now absent from mainland Australia. Together, the paintings provide evidence that local communities were familiar with these animals and considered them significant enough to record in their cultural traditions.
The project demonstrates the growing importance of partnerships between scientists and Traditional Owners. Indigenous custodians played a central role in locating, documenting, and interpreting the artworks. Their knowledge of Country, cultural history, and rock art traditions helped guide the research while ensuring that cultural values remained central to the study.
Increasingly, researchers are recognizing that Indigenous knowledge can complement scientific investigation in powerful ways. Oral histories, cultural practices, and traditional ecological knowledge often preserve information about landscapes and species that may not be captured in archaeological records alone. By combining these perspectives, scientists can develop a richer understanding of environmental change over time.

Dating rock art remains challenging, and researchers caution against drawing firm conclusions about extinction timelines based solely on the newly discovered images. Determining the age of paintings often requires analyzing surrounding materials, stylistic characteristics, and archaeological evidence. Even so, the possibility that some artworks may be less than 1,000 years old has generated significant interest among researchers studying Australia’s extinct fauna.
The discovery also contributes to broader discussions about extinction and biodiversity loss. The thylacine remains an enduring symbol of the consequences of species decline, particularly after the last known individual died in captivity in 1936. Today, the animal continues to capture public imagination through conservation discussions, scientific research, and even debates about de-extinction technologies.
Yet the significance of Tasmanian tiger rock art in Arnhem Land extends beyond the thylacine itself. The paintings highlight the deep connections between Indigenous communities and the wildlife that once shared their landscapes. They remind us that cultural heritage sites can preserve valuable ecological information while maintaining living links to history and tradition.
The findings also underscore the importance of protecting Indigenous cultural landscapes. Many rock art sites face threats from erosion, climate impacts, and human disturbance. Preserving these places safeguards not only cultural heritage but also opportunities for future scientific discoveries that may deepen our understanding of Australia’s past.
As researchers continue studying Tasmanian tiger rock art in Arnhem Land, the newly documented images offer a fascinating glimpse into a world that once existed across the Australian continent. By bringing together Traditional Owner knowledge and scientific research, the project is revealing new perspectives on extinct species while celebrating the enduring cultural stories preserved in Arnhem Land’s remarkable rock art traditions.
