Taxonomy
Calycoceras was named by Hyatt (1900) [Sepkoski's age data: K Ceno-l K Ceno-u]. Its type is Ammonites navicularis.
It was assigned to Mantelliceratinae by Cooper (1978); to Acanthoceratidae by Matsumoto (1959), Cobban (1972), Zaborski (1985), Matsumoto and Skwarko (1991) and Matsumoto and Skwarko (1993); to Ammonoidea by Sepkoski (2002); and to Acanthoceratinae by Kennedy and Simmons (1991), Kennedy (1994), Wright et al. (1996), Kennedy et al. (1996), Kennedy et al. (1996), Barroso-Barcenilla (2004), Kennedy and Jolkicev (2004), Ahmad et al. (2013), Kennedy (2013), Sharifi et al. (2016), Gale et al.

Diagnosis
Reference | Diagnosis | |
---|---|---|
C. W. Wright et al. 1996 | Rather evolute, with whorl section depressed and subcircular, oval, polygonal, or subquadrate; ribs strong, generally straight, continuous over rounded or flat but not concave venter; on early whorls at least umbilical, ventrolateral, siphonal, and, in most specimens, midlateral tubercles; in multituberculate forms umbilical tubercle more prominent than midlateral; tubercles may disappear with age and may or may not be rejuvenated on last part of shell. Marked dimorphism in size apparently general. Contrary to the situation in Mantelliceras, a number of subgenera are here accepted because there are significant morphological and, to some extent, time gaps between species groups. |
