When: Gonda Formation, Messinian (7.2 - 5.3 Ma)

• Age from Kimura 2009.

•

•The Gonda Formation is frequently referred to as the lowermost member of the Shigarami Formation [123]. A K-Ar date of 6.1 Ma for the Koso Tuff, which forms part of the underlying Ogawa Formation, and 5.9 Ma for a lava deposit forming part of the upper Shigarami Formation [124] constrain the age of E. shinshuensis to the Messinian.
