研究人员在澳大利亚西澳皮尔巴拉地区的朱坤2岩shelter发现了袋獾的化石证据，证明这种动物曾在4.5万年前与人类共存于澳大利亚内陆。1此次发现包括一块距今6900-7300年的下颌骨和一颗距今42500-47100年的前臼齿，这是该地区首次明确发现袋獾的骨骼遗骸。1
研究团队检查了8000多件动物骨头样本，其中至少10件骨头显示有袋獾的啃咬痕迹，另有263件消化骨头碎片被分析。1这些证据表明，袋獾可能长期依靠人类营地的食物残骸作为食物来源。1袋獾最终在约3200年前从澳大利亚大陆消失，这一时间与野狗的抵达相关。1相关研究已发表于《大洋洲考古学》期刊。1
Researchers have uncovered fossil evidence of Tasmanian devils in the Pilbara region of outback Western Australia, providing the first definitive skeletal proof that these carnivorous marsupials inhabited Australia's interior alongside people in the distant past 1. The discovery at Juukan Gorge 2 rockshelter includes a jawbone fragment dated to between 6,900 and 7,300 years ago and a premolar tooth ranging from 42,500 to 47,100 years old, demonstrating that Tasmanian devils were present in the area when human activity at the site extended back at least 47,000 years 1.
The analysis of over 8,000 animal bone samples revealed that Tasmanian devils likely sustained themselves on food scraps left at human campsites, with at least 10 of 55 examined bone samples bearing Tasmanian devil bite marks 1. The research, published in the journal Archaeology in Oceania, also examined 263 fragments of digested bone pieces, further illuminating the dietary patterns of these animals 1. The findings suggest that Tasmanian devils persisted on mainland Australia until approximately 3,200 years ago, after which they disappeared—a timeline that coincides with the arrival of dingoes on the continent 1.
