Cephalopoda - Ammonitida

Taxonomy

Psilocerataceae was named by Hyatt (1867). Its type is Psiloceras.

It was corrected as Psiloceratoidea by Meister and Friebe (2003), Hillebrandt (2006), Macchioni et al. (2006), Yin et al. (2007), Blau et al. (2008), Howarth (2013), Edmunds et al. (2016) and Riccardi (2019).

It was assigned to Psiloceratina by Hall et al. (2000); to Psiloceratida by Meister and Friebe (2003) and Blau et al. (2008); and to Ammonitina by Wiedmann (1970), Thomson and Smith (1992), Corna and Dommergues (1995), Smith and Tipper (1996), Blau (1998), Blau et al. (2000), Delsate et al. (2002), Donovan and Surlyk (2003), Hillebrandt (2006), Macchioni et al. (2006), Yin et al. (2007), Howarth (2013), Edmunds et al. (2016) and Riccardi (2019).
