Where: Aomori, Japan (41.4° N, 141.4° E: paleocoordinates 41.4° N, 141.4° E)
• coordinate estimated from map
When: Middle Pleistocene (0.8 - 0.1 Ma)
• No direct dating is available for the fossil localities, but the occurrence of marine vertebrates and the inclusion of marine-originated sediments indicate that the fossil-bearing layers had been deposited near the past sea level (Nakajima and Kuwano 1957; Nakajima 1958; Hasegawa et al. 1988). Therefore, the localities can be correlated to certain marine terrace surfaces; Loc. 2 (70–80 m above sea level) can be correlated to the Toei surface (65–80 m; MIS 9).
