The name Cerion is based on the Greek word kerion, signifying honeycomb, and is given to these shells because the form of the shell resembles that of a beehive; hence they were at one time known as beehive shells.[4]

The fossil range of Cerion is possibly from the Upper Cretaceous of Montana, or the early Miocene of Florida.[1] Records of Cerion in Pleistocene are rare.[1]
