Uryu | Horikawa H. (1977) | Shintotsukawa - Mashike - Lower Mud | 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. | mudstone | 11.62 - 7.246 Ma Miocene |
