The Gawis cranium is a fossilized hominid skull discovered on February 16, 2006 near the drainage of Gawis, a tributary of the Awash River in the Afar Depression, Ethiopia. The skull is between 200,000 and 500,000 years old and appears to be an intermediate species between Homo erectus and Homo sapiens. Scientists suspect the skull could be a transitional fossil that fills a gap in human evolutionary origins.
