Arago 21 is a deformed cranial fragment dated to approximately 450,000 years. The skull was found by H. Lumley and M.A. Lumley in the Arago Cave located at Tautavel France. The hominid was twenty years old as indicated by the state of the fronto-pariental suture, and the gender is thought to be male. Archaeologists were uncertain of the age of the hominid, although finding the morphology comparable to the Petralona skull that is accepted as a Neanderthal of the Upper Pleistocene variate, paleoanthropologists (Cartmill, Smith, et al) have classified the skull instead as Heidelberg.
