Tornoceras
Taxonomy
Tornoceras was named by Hyatt (1884) [Sepkoski's age data: D Give-l D Fame-m Sepkoski's reference number: 302,457]. It is not extant. It is the type genus of Tornoceratidae, Tornoceratinae.
It was reranked as Goniatites (Tornoceras) by Frech (1887); it was reranked as Gomimonomeroceras (Tornoceras) by Sobolew (1914).
It was assigned to Goniatites by Frech (1887); to Gomimonomeroceras by Sobolew (1914); to Goniatitida by Sepkoski (2002); and to Tornoceratinae by Korn and Klug (2002), Korn (2006), Bockwinkel et al. (2013), Bockwinkel et al. (2013), Bockwinkel and Korn (2015) and Söte et al. (2021).
