Where: Saitama, Japan (36.0° N, 139.0° E: paleocoordinates 39.5° N, 136.4° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Nagura Formation (Chichibumachi Group), Burdigalian to Burdigalian (20.4 - 13.8 Ma)

• The Nagura Formation forms the lowermost part of the Chichibumachi Group, which correlates with foraminiferal zone N8 [51, 110, 111] and thus spans the Burdigalian- Langhian boundary (16.4–15.1 Ma) [20, 54]. (Marx & Fordyce, 2015)

• formation-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithology not reported

Size class: macrofossils
