Taxonomy
The taxonomy of the Cheiloceratidae varies according to the perception of different researchers over time and can be considered a work in progress. That presented in the taxobox is simply one of the more recent.
Cheiloceratidae is the larger of two families included in the Cheilocerataceae in the 1957
The Russian Osnovy Paleontologii, by Bogoslovsky et al,[4] placed the Cheiloceratidae, in the sense of the Cheiloceratinae of the Treatise, in the superfamily Dimeroceratoidea (ex Dimerocerataceae) which is included in the suborder Tornoceratina. Sister families to the Cheiloceratidae in the Dimeroceratoidea [4] are the Dimeroceratidae, Phenacoceratidae, Prolobitidae, and Sinotitidae.
Saunders et al[2] includes the Cheiloceratidae in the suborder Tornoceratina along with the Maenioceratidae, Tornoceratidae, Sinotitidae, Posttornoceratidae, Sporadoceratidae, and Dimeroceratidae; without the use of a superfamily.
In the more recent taxonomy attributed to Dieter Korn in 2006[3] the Cheiloceratidae is included in the Prionocerataceae and includes two subfamilies, the Cheiloceratinae and Nehdenitinae.
