Mysterious 286,000 Year Old GREEK Skull Has Anthropologists Perplexed

The Petralona skull is both hauntingly familiar and strangely alien. Its brow is a heavy torus, prominent and robust, yet internally hollow—a feature that distinguishes it sharply from both modern Homo sapiens and classic Neanderthals. This hollowing of the browridge was later found to be filled with extensive frontal sinuses, and it is this feature, among others, that positions Petralona at a fascinating crossroads between primitive and derived traits. While its massive upper face and browridge evoke the brutishness of Homo erectus, its vault and endocranial volume suggest a species on the cusp of becoming recognizably human. Its resemblance to the Kabwe skull of Zambia, another enigmatic fossil dated to a similar range, underscores the notion of a widespread Middle Pleistocene population that straddled the evolutionary boundary between Homo erectus and Homo sapiens, and which may have included the ancestors of the Neanderthals.
