Hoplitinae

Belongs within: Hoplitaceae.

The Hoplitinae are a Cretaceous (Middle Albian to Lower Cenomanian) lineage of strongly ribbed ammonites (Wright et al. 1996).

Characters (from Wright et al. 1996): Venter flat, grooved, or slightly rounded; ribs interrupted on venter, with peripheral endings alternate; ribs branching from umbilical tubercles and commonly ending in prominent ventrolateral clavi; ribs repeatedly tending to unite in pairs at clavi. Large individuals with adult body chamber nearly smooth and with rounded venter are presumed to be macroconchs.
