The territory currently known as the United Arab Emirates was formerly populated by inhabitants of a number of coastal and inland settlements, with human remains pointing to a pattern of transmigration and settlement as far back as 125,000 years. Prehistoric settlement in the UAE took place in the Neolithic, with a number of distinctive eras of ancient settlement including the Stone Age Arabian Bifacial and Ubaid cultures from 5000 to 3100 BCE; the Hafit period with its distinctive beehive shaped tombs and Jemdet Nasr pottery, from 3200 to 2600 BCE; the Umm Al-Nar period from 2600 to 2000 BCE; the Wadi Suq Culture from 2000–1300 BCE and the three Iron Ages of the UAE.
