This page lists the 53 genera that have at least one albian species described on this website.
The classification used comes from the Treatise of Invertebrate Paleontology (Wright, 1996), in the same order, but with a few exceptions listed at the end.
If you are not familiar with this order, the site map provides an access to all genera and their species in alphabetical order.
List of changes to the list of genera compared to Wright's "Treatise" (1996) :
The genus Goretophylloceras is synonymous with Hypophylloceras for Wright et al. We follow Jolly (1993), who considers them to be two distinct subgenera of genus Phylloceras.
Restructuring of the Hoplitidae family. The subfamily Anahoplitinae is suppressed. Its genus Anahoplitoides is moved to the subfamily Sonneratiinae, while its two other genera Anahoplites and Pleurohoplites are transferred to the subfamily Hoplitinae. The genus Otohoplites is moved from the subfamily Sonneratiinae to the subfamily Hoplitinae. This restructuring, justified by phylogenetic reasons, is followed, for example, by Amédro et al. (2014).
Following the revision by Riccardi and Medina (2002), in the superfamily Desmocerataceae, the genus Aioloceras is moved from the family Desmoceratidae, subfamily Pseudosaynellinae, to the family Cleoniceratidae.
The genus Prolyelliceras, classified by Wright in the family Lyelliceratidae, actually contains homeomorphs of Lyelliceras, with different ancestors. We follow Latil, Robert, and Bulot (2009) who place it in a new family, the Prolyelliceratidae.
Like Cecca (1997), we transfer the genus Semenoviceras from the subfamily Hoplitinae to that of Anahoplitinae, within the family Hoplitidae.
Rhytidoceras is considered by Wright to be one of the two subgenera of Dipoloceras. We follow Kennedy & Klinger (2023) who make it a separate genus, which means that Dipoloceras no longer has subgenera.
