Other finds have included pottery from the Al Ubaid culture of Mesopotamia and northern Arabia (ca. 5000 B.C.), rock carvings, burial mounds, and a large town that dates from about 500 B.C. at Wusail, some twenty kilometers north of Doha. The Qatar Peninsula was close enough to the Dilmun civilization (ca. 4000 to 2000 B.C.) in Bahrain to have felt its influence. A harsh climate, lack of resources, and frequent periods of conflict, however, seem to have made it inevitable that no settlement would develop and prosper for any significant length of time before the discovery of oil.
