Chippewaella patellitheca is a stem-gastropod mollusc from Furongian-aged strata of Late Cambrian Wisconsin.^[1] According to Peter J. Wagner, it is the most basal gastropod.^[2]

Morphology edit

C. patellitheca is known from broad, low, cap-shaped or mound-shaped shells around 2 centimeters in diameter. The shell has a slight apex that points posteriorly, and is at the posterior end of a central dorsal ridge.^[1]
