I'm working on some middle Miocene fossil mollusks from southern Orange
County, southern California and have an internal mold that matches in shape
fairly well with Protothaca costellata (Sowerby) illustrated in Axel A.
Olsson (1961, Mollusks of the tropical eastern Pacific. Panamic-Pacific
Pelecypoda: Paleontological Research Institute, Ithaca, pl. 49, f. 3). But
I can find no further record of that species in Olsson or elsewhere. Any
help running down the species name or what that species is now called would
be appreciated.
Best,
Chuck
