Berniceras is an extinct ammonite genus from the order Ammonitida that lived during the early Oxfordian stage of the Late Jurassic.[1] Berniceras is included in the ammonite (sensu stricto) family, Oppeliidae.

Bernceras, which has been found in Europe, has a moderately enlarging, ribbed, involute shell with a keel along the venter, which forms the outer rim. The ribs are formed on the outer flanks and curve forward ventrally.
