The area of present-day Morocco has been inhabited since at least Paleolithic times, beginning sometime between 190,000 and 90,000 BC. A recent publication has suggested that there is evidence for even earlier human habitation of the area: "Homo sapiens" fossils that had been discovered in the late 2000s near the Atlantic coast in Jebel Irhoud were recently dated to roughly 315,000 years ago. During the Upper Paleolithic, the Maghreb was more fertile than it is today, resembling a savanna, in contrast to its modern arid landscape. Twenty-two thousand years ago, the pre-existing Aterian culture was succeeded by the Iberomaurusian culture, which shared similarities with Iberian cultures. Skeletal similarities have been suggested between the human remains found at Iberomaurusian "Mechta-Afalou" burial sites and European Cro-Magnon remains. The Iberomaurusian culture was succeeded by the Beaker culture in Morocco.
