Where: Fukushima, Japan (42.8° N, 143.0° E)

• Paleocoordinates: 42.7° N, 142.3° E (Wright 2013)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: N21 foram zone, Futatsu-numa Sand Member (Tomioka Formation), Late/Upper Pliocene (3.6 - 2.6 Ma)

• LITHOSTRATIGRAPHY: From Futatsu-numa Sand (informal) member of the Tomioka Formation, Taga Group. STRATIGRAPHIC RELATIONS: From basal sand (30 m) of 100 m thick Tomioka Formation THICKNESS: 30 m thick. AGE: Molluscan biostratigraphy suggests a Pliocene age. Micropaleontological data indicates the Futatsu-numa Sand is included in the Globoratalia tosaensis Zone (N21) of the planktonic foraminiferal zonation and is contained in the Denticulopsis seminae var. fossils-Denticulopsis kamtschatica diatom Zone, and its age is estimated to fall between 2.5 and 3.5 Ma.
