   Stylophorans are divided into two orders the Cornuta and Ankyroida: cornutes have asymmetrical thecae, aulacophores with stylocones and cover plates over the food groove that open widely; ankyroids have essentially bilaterally symmetrical thecae, aulacophores with styloids and in most the cover plates do not open widely.
