Extract

Gastropods are rare fossils in the Cambrian of Wisconsin. They are usually small and flattened. During the summer of 1978, while collecting trilobites along the western side of the state, I discovered a new gastropod in the Crepicephalus zone (as defined by Twenhofel, Raasch, and Thwaites, 1935; Nelson, 1951). It is a three-dimensional fossil represented by external mold and steinkern. This was the only gastropod uncovered during the splitting of over 200 kilograms of sandstone, which also yielded hundreds of trilobite cranidia and pygidia.
