Where: Saitama, Japan (36.0° N, 139.1° E: paleocoordinates 39.5° N, 136.4° E)
• coordinate estimated from map
When: N8 foram zone, Nagura Formation (Chichibumachi Group), Burdigalian to Burdigalian (20.4 - 13.8 Ma)
• late Burdigalian-Langhian (16.4–15.1 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
