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.
Nobody rocks harder than a 70s funk-rock band with two drummers.
…the old-school way, with paperclips. David Hurst Thomas illustrates:
“Seriation diagrams were once constructed by hand (literally). Frequencies of temporal types were converted to percentages, then drawn on individual strips, which were then moved up or down until they approximated a series of battleship-shaped curves (Ford, 1962: fig.8). This tedious and subjective procedure has since been replaced by computer programs.”
