The area currently known as the United Arab Emirates (UAE) (previously the Trucial States) 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 spanned the Neolithic, with a number of distinctive eras of ancient settlement including the Stone Age Arabian Bifacial and Ubaid cultures from 5,000 to 3,100 BCE; the Hafit period with its distinctive beehive shaped tombs and Jemdet Nasr pottery, from 3,200 to 2,600 BCE; the Umm Al Nar period from 2,600 to 2,000 BCE; the Wadi Suq Culture from 2,000–1,300 BCE and the three Iron Ages of the UAE.
