The Mint Canyon fauna. presumably occupies a position between the

W1a.scall and the Coalinga (Temblor or Topanga) fauna.l stages of the Miocene

on the one hand and the Barstow on the other. This position would indicate

apparently an upper middle Miocene or lower upper Miocene age. Several

considerations lead the writer to favor an upper middle Miocene age for

the Mint Canyon formation.
