Cephalopoda - Ammonitida - Ancyloceratidae

Taxonomy

Ancyloceratidae was named by Gill (1871). Its type is Anclyoceras.

It was assigned to Hamitaceae by Wright (1952); to Ancyloceratina by Murphy (1975); to Ancyloceratoidea by Delanoy et al. (2013); and to Ancylocerataceae by Cantu-Chapa (1962), Förster (1975), Cooper and Kennedy (1979), Aguirre-Urreta (1986), Klinger and Kennedy (1992), Reboulet (1996), Kakabadze and Hoedemaeker (1997), Landra et al. (2000), Szives (2007), Frau et al. (2016), Robert et al. (2018) and Ovando-Figueroa et al. (2018).

Synonyms

Tonoceras was named by Hyatt (1900) [Sepkoski's age data: K Barr-u]. It is not extant.

It was reranked as Ancyloceras (Tonoceras) by Wright et al. (1996); it was considered a nomen nudum by Frau et al. (2022).
