对先前关于贝壳和木炭日期之间的冲突以及烧焦的人骨之间的冲突的结果进行的新分析以及此处提供的新数据表明，威兰德拉湖地区的考古学和环境历史可能有其他解释。外阿鲁姆波湖考古遗址的黑色沉积物样本在燃烧和未燃烧的碳含量方面表现出很大的差异；中层和一组炉床/烤炉中的高腐殖酸浓度在另一组较旧的炉床/烤炉中不存在。对于来自年龄超过约 10 年的炉灶/烤箱的木炭，没有可接受的结果。 31 ka bp，没有证据表明这些样本与许多 34-37 ka bp 的贝壳年代有关。类似的逻辑适用于烧焦的人骨上的无腐殖质残留物日期，将五个细长骨骼（包括 Mungo 1）视为末次盛冰期后。
A new analysis of previous results on conflicts between shell and charcoal dates and on burnt human bones, with new data presented here, suggests that alternative interpretations are possible for the archaeology and environmental history of the Willandra Lakes region. Black sediment samples from archaeological sites at Lake Outer Arumpo exhibit wide variation in burnt and unburnt carbon content; high humic acid concentrations in midden layers and in one group of hearth/ovens are absent in another, older, group of hearth/ovens. There are no acceptable results on charcoal from hearth/ovens older than ca. 31 ka bp, and no evidence that these samples are associated with numerous midden shell dates at 34–37 ka bp. Similar logic applied to humic-free residue dates on burnt human bones places five gracile skeletons (including Mungo 1) as post–Last Glacial Maximum.
