Wagner, it is the most basal gastropod.[2] MorphologyC. 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]References1. ^1 2 Gunderson, G. O. 1993. New genus of Late Cambrian gastropod.
