Living the Scientific Life (Scientist, Interrupted)


Turritella perattenuata fossil, next to a nickel (for scale).
Caloosahatchee fm[1]., Brandtley quarry, near Highway 31, Florida.

This is a Caloosahatchee fossil, the remarkably elongate and now-extinct Turritella perattenuata. The Caloosahatchee is said to straddle the Plio-Pleistocene boundary, which, according to the Geological Society of America Geological Time Scale, occurs at 1.8 Myr. The Caloosahatchee fauna is tropical, but the Lower Pleistocene Bermont formation above it in the South Florida section shows temperate elements.

    I must say, they are smaller than I had been led to believe.
