Fissilobiceras is a smooth, compressed, involute ammonite from the lower Middle Jurassic of Europe, named by Buchman in 1919. It is assigned to the hildoceratoid family, Hammatoceratidae.

Fissilobiceras is similar to , except primarily for being more involute and having complex sutures. More of the inner whorls show in Shirbuirnia and its sutures are simple. Fissilobiceras also has a low keel running along the venter and only a small part of the inner whorls are exposed in the small umbilicus.
