Glycymeris cookei

Phylum Mollusca
Class Bivalvia

(Scale bar is 1 cm)

 

 

This small bivalve is easily recognized, often even as molds in the Oligocene residuum of the Dougherty Plain. The reason is that the general shape of the shell, coupled with the taxodont dentition, is very characteristic. The figure at right shows a sketch of the taxodont dentition of Glycymeris sp. with its multiple aligned teeth and sockets.

This species is known from the Bridgeboro Limestone and Oligocene residuum of southwestern Georgia, and is a good guide fossil for lower Oligocene rocks in the southeast.
