Balticeras is an involute, discoidal Upper Jurassic (Oxfordian) ammonite<ref name="Sepkoski Ceph">{{cite web

Balticeras is considered by some to be a subgenus of Ringsteadia which in contrast is more evolute, with ribbed inner whorls. Both are included in the Pictoniinae, a subfamily established by Spath, 1924, for large ammonites within the Perisphinctidae, tending to develop smooth middle and outer whorls.
