Shiriya, Locality 3-2 (Pleistocene of Japan)

Where: Aomori, Japan (41.4° N, 141.4° E: paleocoordinates 41.4° N, 141.4° E)

• coordinate estimated from map

When: Late/Upper Pleistocene (0.1 - 0.0 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. 1 (~45 m above sea level) and Loc. 3 (~35 m) to the Tonamigaoka surface (35–45 m; MIS 5e).

Environment/lithology: fissure fill; lithology not reported

Size class: macrofossils
