White Sands footprints, North America
Observation: Human trackways occur on former lake and wetland surfaces at White Sands National Park, New Mexico. The footprints themselves are physical evidence of people walking across those surfaces. The key question is their age, rather than whether a stone-tool type has been correctly…
Dated material: Aquatic seeds, terrestrial pollen, quartz and wetland mud.

Observation: At Cape Bruguieres Channel in Murujuga, northwestern Australia, divers mapped hundreds of stone artifacts in a shallow channel. The 2020 project paper interprets much of the assemblage as remaining on a land surface submerged by postglacial sea-level rise. The Deep History of Sea Country project was undertaken with the approval of the…
Dated material: Inundation model; the stone artifacts were not directly dated.
Reported constraint: ≥c. 7 ka only if pre-inundation
Observation: A human femur from western Siberia was directly radiocarbon dated to roughly 45 ka and sequenced at high coverage. The researchers identified Neanderthal-derived genomic segments that were longer on average than in many living people. From their lengths, they estimated gene flow into ancestors of this individual roughly 7,000–13,000…
Dated material: Directly dated femur; genome used for admixture modeling.
Reported constraint: c. 45 ka; uncertainty not quantified here
