The presence of Aboriginal people in interior refuges as climate conditions deteriorated with the onset of glacial aridity is now well documented in the Australian arid zone. Further excavation at Yurlu Kankala, a large rock shelter located on an island of high land in the inland Pilbara, demonstrates repeated human occupation from at least 47–43 cal ka BP through the Last Glacial Maximum to the mid‐Holocene. Despite the continued presence of bone representing human food remains and an increased occurrence of hearths, after 18–17 cal ka BP there is a dramatic reduction in stone artefact numbers, suggesting that use of the site changed markedly. In exploring the drivers behind this change, we investigate the role of rock shelters in Aboriginal land‐use systems in the Pleistocene Pilbara. Yurlu Kankala makes a substantive contribution to answering questions on changing rock shelter and landscape use during the post‐LGM movement of people into the wider Pilbara uplands.

在最后一次冰河期之后，发生了什么？澳大利亚西北部干旱内陆岛上的场地使用过渡

随着澳大利亚干旱地区气候条件的恶化和冰川干旱的爆发，土著居民在室内避难所的存在得到了充分的记录。在尤尔·坎卡拉（Yurlu Kankala）进行的进一步发掘是位于内陆皮尔巴拉（Pilbara）内陆高地岛上的一个大型岩石避难所，表明人类从至少47–43 cal ka BP直到最后一次冰河期到全新世中期都被反复占领。尽管持续存在代表人类食物残骸的骨头并增加了炉膛的发生，但在18-17 cal ka BP之后，石制品的数量显着减少，这表明该部位的使用发生了显着变化。在探究这一变化背后的驱动因素时，我们研究了岩石掩体在更新世皮尔巴拉原住民土地利用系统中的作用。
