Belongs within: Gephuroceratina.
Manticoceras is a genus of ammonoid from the Upper Devonian, of which some species were only about 15 mm in diameter. A number of species of this genus have been used as index fossils for stratigraphic dating (House 1979; Norris 1979).
Characters (from Kirchgasser 1975): Compressed, subevolute conch. Suture with six primary lobes; umbilical lobe strongly developed, typically acute.
