Taxonomy
Baculites was named by Lamarck (1799) [Sepkoski's age data: K Turo-u K Maes-u Sepkoski's reference number: 2,971]. Its type is Baculites vertebralis. It is the type genus of Baculitinae.
It was assigned to Baculitinae by Brunnschweiler (1966) and Förster (1975); to Ammonoidea by Sepkoski (2002); and to Baculitidae by Reyment (1955), Benavides-Caceres (1956), Matsumoto (1959), Henderson (1970), Kennedy et al.
