Where: Hokkaido, Japan (43.7° N, 141.7° E: paleocoordinates 44.1° N, 140.4° E)

• coordinate stated in text

When: Lower Mud Member (Mashike Formation), Tortonian (11.6 - 7.2 Ma)

• the potential age of Eodelphis is between 8.5 and 13.0 Ma. However, the maximum age of Eodelphis may be relatively younger (ca. 9 Ma) within this range, because the holotype came from near the upper limit of the mud- stone unit of the Mashike Formation.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; mudstone
