Late Devonian Brachiopod Fossils Preserved as Molds in a Fine-Grained Sandstone

Caption

Late Devonian brachiopod fossils were preserved as molds in a fine-grained sandstone (Big Creek, Hornell, New York, N 42.364361, W 77.645760). Individual fossil samples like this are the basis for testing the effects of biases on the global record of biodiversity history.
