Kepplerites
Encyclopedia
Kepplerites is a moderately evolute ammonite from the lower Callovian
(upper Middle Jurassic
) included in the Stephanocerataceae.
Inner whorls are finely ribbed and have a flattened or grooved venter, the outer whorl has a rounded venter with smooth ribs that cross from side to side without interruption.
Kepplerites is assigned to the Kosmoceratidae and to the subfamily Keppleritinae. Gulielmina and Seymourites are closely related genera, sometimes regarded as subgenera of Kepplerites.
Kepplerites was named by Neumayr and Uhlig in 1892. The type species K keppleri is from Germany. This genus has also been found in Alaska, British Columbia, Madagascar, and Russia.
