Recent research utilizing advanced fossil analysis is upending the long-held belief that Australia’s First Peoples hunted the continent’s megafauna to extinction. Instead, evidence now suggests ancient Indigenous Australians were keen fossil collectors, valuing and transporting ancient bones as cultural objects, implying a sophisticated coexistence with these giant animals before climate change led to their disappearance.
For decades, the prevailing scientific theory suggested that when Australia’s First Peoples arrived on the continent some 65,000 years ago, their hunting prowess led to the extinction of the magnificent megafauna that once roamed the land. These colossal creatures, including giant long-nosed echidnas, nearly 10-foot tall short-faced kangaroos, and wombat-like marsupials the size of rhinos, vanished by approximately 46,000 years ago.
However, recent groundbreaking research is challenging this long-held assumption, offering a compelling new interpretation: Indigenous Australians may have valued these large animals not just for sustenance, but also for their bones as cultural objects. This nuanced perspective suggests a far more complex relationship between early humans and their environment than previously understood.
Re-examining the Evidence: The Kangaroo Tibia and Wombat Tooth
The catalyst for this paradigm shift comes from the re-analysis of two significant fossils, both approximately 50,000 years old. One is a fossilized kangaroo tibia found between 1909 and 1915 at Mammoth Cave in southwestern Australia. In the 1960s, a human-made cut mark on this tibia was interpreted by scientists as definitive proof of butchering, supporting the “over-killing” hypothesis.
Dr. Michael Archer, lead author of the new study and a professor at the University of New South Wales (UNSW) in Sydney, had coauthored a paper in 1980 supporting this initial interpretation. However, the advent of more sophisticated analytical tools by 2013 prompted a deeper look. He tasked study coauthor Dr. Blake Dickson with performing a micro-CT scan of the fossil.
The micro-CT scans, which allow scientists to examine internal bone structures without damage, revealed a surprising truth. Dr. Archer stated, “That’s when we were shocked to find that the evidence clearly indicated the cut had occurred on the bone only after the bone had already become a fossil.” The presence of multiple longitudinal cracks indicated it had dried out before becoming part of the fossil deposit, and a crosswise fracture in the cut area happened after desiccation. This crucial finding rules out butchering, suggesting the preserved bone itself was the object of interest.
The second piece of evidence comes from a premolar of the extinct giant wombat Zygomaturus trilobus. While this marsupial species is common in southern Australian fossil deposits, it is unknown in the north. Yet, an Indigenous man in northern Australia possessed this tooth as a charm, mounted in resin and attached to human hair string. Dr. Archer noted the probability that the tooth “had been collected as a fossil in the southwest of Western Australia and then traded up the coast to the Kimberley region.” This indicates long-distance transport and cultural significance, reinforcing the idea of fossil collection.
These findings were published in the journal Royal Society Open Science, providing a new perspective on the interactions between early humans and Australia’s ancient megafauna.
Indigenous Australians as Ancient Fossil Collectors
The new research strongly suggests that Australia’s First Peoples were not just hunters, but sophisticated fossil collectors, appreciating the aesthetic and cultural value of ancient bones. Dr. Archer passionately shared, “The cut was part of an effort to collect the fossilised bone as a curiosity by First Nations people — they were fossil collectors, just like us!”
This perspective is supported by existing archaeological knowledge. Dr. Judith Field, a UNSW honorary associate professor not involved in the new research, highlighted that Indigenous Australians were already known to use bones and shells as adornment or cultural objects. Examples include shell beads dating back over 10,000 years from Barrow Island, and a 7,000-year-old necklace of Tasmanian devil teeth found near Lake Nitchie.
Dr. Field added, “These findings correlate with what we know about human behaviour. People collect things and move them around the landscape.” This broader understanding of human behavior helps contextualize the new findings, moving away from a narrow view of survival and resource exploitation.
Challenging the “Over-Killing” Hypothesis
This new evidence directly challenges the long-standing hypothesis of human “over-killing” as the primary cause of megafauna extinction in Australia. Dr. Archer emphasized the “lack of hard evidence” to support the idea that First Peoples “were potentially ‘over-killing’ these animals soon after human arrival.”
Instead, the study suggests a prolonged period of coexistence. “In fact, the evidence suggests that humans and these megafaunal animals coexisted for at least 15,000 years,” Dr. Archer explained, adding that the extinctions were “probably until climate change led to the progressive extinction of those animals.” Dr. Field concurs, noting that while some overlap occurred, “climate variability probably also contributed to the extinction of Australia’s largest animals, rather than human hunting alone.” The only site unequivocally placing megafauna and humans in the same place at the same time remains Cuddie Springs.
The authors are not suggesting that Indigenous Australians never hunted large animals, but they caution against the notion of hunting to extinction. Dr. Archer believes this idea “likely originated from Western biases,” influenced by centuries of mass extinction patterns that followed European colonization in Australia.
Western Biases and Sustainable Coexistence
Dr. Archer highlights a critical point: modern European-caused extinction events, largely driven by agriculture and the introduction of non-native species, have perhaps led some scientists to “naively presumed that all peoples in the past similarly created the same kind of mayhem when they first entered new lands.”
This new research encourages a re-evaluation of how we perceive ancient human-environment interactions. Dr. Archer posits, “What we’re suggesting is that, at least in Australia, the First Peoples may well have quickly become an integral part of this continent’s ecosystems, valuing and sustainably utilising this continent’s native biota rather than the alien species involved in unsustainable agricultural practices that we now inflict on this continent.”
The findings offer a powerful narrative of Indigenous Australians as thoughtful stewards of their land, rather than destructive forces. This profound shift in understanding not only redefines ancient history but also encourages us to reflect on contemporary relationships with our planet.
