Nostoceratidae

Belongs within: Turrilitaceae.

The Nostoceratidae are a lineage of heteromorphic ammonites known from the Turonian to Maastrichtian of the Upper Cretaceous (Wright et al. 1996).

Characters (from Wright et al. 1996): Helicoid forms with coiling commonly irregular in early or late stages or both or throughout. Ribs prominent, with or without tubercles; constrictions common. Suture normally florid.
