Diplomoceras

Cephalopoda - Ammonitida - Diplomoceratidae

Taxonomy

Diplomoceras was named by Hyatt (1900) [Sepkoski's age data: K Camp-l K Maes-u Sepkoski's reference number: 971]. Its type is Baculites cylindracea. It is the type genus of Diplomoceratidae, Diplomocerataceae.

It was assigned to Macroscaphitidae by Hyatt (1900); to Desmoceratidae by Lahsen and Charrier (1972); to Ammonoidea by Sepkoski (2002); to Diplomoceratinae by Summesberger (1979), Matsumoto (1984), Kennedy and Summesberger (1986), Macellari (1986), Henderson et al. (1992), Ward and Kennedy (1993), Kennedy (1993), Kennedy (1999), Arkadiev et al. (2000), Ifrim et al. (2015) and Dochev and Metodiev (2016); and to Diplomoceratidae by Brunnschweiler (1966), Henderson (1970) and Kurihara et al. (2016).
