History

The type species, Asklepioceras segmentatum was originally named as Arpadites segmentatus by Renz, 1910. In 1951, it was assigned to Asklepioceras by L. F. Spath. Founded in British Columbia in 1947, A. mahaffii was later synonymised with A. laurenci. Two more species, A. exilis and A. altilis, both from Canada, were described in 1994 by E. T. Tozer.

Description

The genus is characterized by evolute to involute, discoidal to subglobular shells with a median (ventral) furrow not bordered by keels (in contrast to Dittmarites in which it is) and simple ceratitic sutures. (Arkell et al. 1962, L162) The genotype Asklepioceras segmentatus Renz, 1910, based on Arpadites (Dittmarites) segmentatus Mojsisovics, 1893. is found in the Carnian of the Alps.
