From the Smithsonian Institution, here’s a passenger pigeon bone, specifically a left humerus (wing). the Smithsonian only identifies it as being from Bartow County, Georgia, but given the collector is attributed to “Lipps et al,” it is likely from Ladd’s Quarry. In the 1960s, Shorter College biology professor Emma Lewis Lipps excavated at this site and sent many fossils to the Smithsonian.
