This region is known for violence along the colonial frontier, and this kopi site is only one to two days walk from the site of a known massacre of a ceremonial gathering of people at Kaliduwarry waterhole in about 1878. There is no direct evidence showing that this site coincides with colonial expansion in this region in the late 1870s, but the condition of these caps and their geomorphic context indicate that this site cannot be older than a few hundred years. If it dates to the pre-contact period in the 1800s, this kopi site must reflect a higher degree of social ranking and complexity than is usually assumed in the ethnography. Whether or not this remarkable site relates to the death of a single, high-ranked individual or multiple deaths on the colonial frontier in a single event, this cluster of mourning caps indicates t...

Humans colonized the continent by 50 ka, but an apparent lack of cultural innovations compared to people in Europe and Africa has been deemed a barrier to early settlement in the extensive arid zone. Here we present evidence from Warratyi rock shelter in the southern interior that shows that humans occupied arid Australia by around 49 ka, 10 thousand years (kyr) earlier than previously reported. The site preserves the only reliably dated, stratified evidence of extinct Australian megafauna, including the giant marsupial Diprotodon optatum, alongside artefacts more than 46 kyr old. We also report on the earliest-known use of ochre in Australia and Southeast Asia (at or before 49-46 ka), gypsum pigment (40-33 ka), bone tools (...

We also report on the earliest-known use of ochre in Australia and Southeast Asia (at or before 49-46 ka), gypsum pigment (40-33 ka), bone tools (40-38 ka), hafted tools (38-35 ka), and backed artefacts (30-24 ka), each up to 10 kyr older than any other known occurrence. Thus, our evidence shows that people not only settled in the arid interior within a few millennia of entering the continent, but also developed key technologies much earlier than previously recorded for Australia and Southeast Asia.
