Chione bainbridgensis is a species of extinct bivalve from the Oligocene of Florida, Louisiana,[1] Georgia, and Mississippi. It is found in the Suwannee Limestone in Florida and the Vicksburg Group in Georgia and Louisiana.[2]
Evolutionary history
Chione bainbridgensis is an early species of Chione, that appeared soon after the Chesapeake Bay Impact Event. [3] It is predated by the Late Eocene Chione craspedonia, and there is evolutionary continuity with the later species Chione chipolana of the Miocene.
