Seto-Obata Locality ( of Japan)

Where: Aichi, Japan (35.0° N, 137.0° E: paleocoordinates 42.3° N, 132.8° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Seto Porcelain Clay Formation (Seto Group), Tertiary (66.0 - 2.6 Ma)

• The Seto Porcelain Clay Formation around the Itoh and Hohtoku Mines in Obata area is 20 to 30 m thick, which unconformably overlies Mesozoic and Paleogene granitic rocks of large relief and is correlated with the Mizunami Group in Tajimi region by the molluscan fauna.
