Arpadites is a genus of ceratitids in the family Trachyceratidae[1] from the Middle and Upper Triassic (Ladinian and Carnian stages) of Nevada (United States ),[2] Alps, Italy, Balkans, Himalayas, and Japan . (Arkel et al. 1962, L162)
The genotype Arpadites arpadis came from the upper Middle Triassic (Ladinian) of the Alps in Europe.
