Sphaerocypraea wegeneri keenae
Taxonomy
Eocypraea (Apiocypraea) keenae was named by Woodring (1959) [DISTRIBUTION: Miocene; circum-Caribbean.]. Its type specimen is USNM 562604, a shell, and it is a 3D body fossil. Its type locality is Woodring Loc. 155 - Gatun Third Locks [middle Gatun Fm], which is in a Tortonian marine sandstone/siltstone in the Gatun Formation of Panama.
It was synonymized subjectively with Sphaerocypraea wegeneri by Dolin and Dolin (1981); it was recombined as Sphaerocypraea wegeneri keenae by Perrilliat (1987).
