Bruniquel Cave Stalagmite Walls Redated to 176,000 Years Ago, Confirming Neanderthal Authorship

New uranium series dating of mineral crusts on stacked stalagmites in Bruniquel Cave, France, pushes the construction date of two stone circles back to approximately 176,500 years ago. This revision supersedes earlier radiocarbon estimates of 47,000 years, confirming that Neanderthals, not early modern humans, built the structures. The discovery highlights advanced Neanderthal capabilities in coordinated labor, fire management, and spatial organization deep underground.

Greek Skull Rewritten: A 300,000-Year-Old Relic Belongs to Homo Heidelbergensis

A 300,000-year-old skull found cemented in a Greek cave (the Petralona cranium) has been dated to at least 286,000 years old via uranium-series dating of the surrounding calcite, placing it with Homo heidelbergensis rather than Homo sapiens or Neanderthals. This suggests a widespread Middle Pleistocene population in Europe that coexisted with Neanderthals for over 100,000 years. No DNA can be recovered due to the long warm history of the fossil, and the find adds complexity to how scientists categorize early human relatives.
