Where: Japan (43.1° N, 142.2° E: paleocoordinates 50.9° N, 134.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Yezo Group, Early/Lower Turonian (93.5 - 89.3 Ma)

• Referred to the Lower Turonian because Mammites sp. was found at loc. Y5112 below Y6014 and Mytiloides mytiloides occurs abundantly at Y6013, stratigraphically above Y6014.

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified siliciclastic sediments

Size class: macrofossils

Preservation: cast, mold/impression
