Archaebranchinecta barstowensis is a species of fairy shrimp (Anostraca) that inhabited California during the Middle Miocene (13.4 million years ago).[1] Its fecal material is abundant in the concretions from the Barstow Formation.[2] A limited number of whole specimens have been found, and they represent the "best-preserved fossil anostracan known to date".[1] The closest relative of A. barstowensis appears to be Archaebranchinecta pollicifera from the surroundings of Lake Titicaca,[1] and the two have been separated from the genus Branchinecta as the new genus Archaebranchinecta.[3]
