Asiatoceratodus sharovi
Complete skeletons of Asiatoceratodus sharovi first described by Vorobyeva (1967) from the Middle-Late Triassic deposits of Fergana valley in Kyrgyzstan. This species is characterizes by toothed plates with 4 to 5 crests.

Asiaticeratodus tiguidiensis
Another species originally was described from the Late Jurassic site of Algeria as Ceratodus tiguidiensis Later, C. tiguidiensis was assigned to Arganodus by M. Martin (1984) and reassigned by Kemp (1998) to the genus Asiatoceratodus. Despite this, some authors uses Arganodus tiguidiensis in their articles. A. tiguidiensis was also found in the Late Jurassic (Kimmeridgian) Tacuarembo Formation of Uruguay, the northwestern Ethiopian plateau of latest Jurassic (Tithonian) age, the Cretaceous Elrhaz Formation of Niger, the Early Late Cretaceous assemblage of Southeastern Morocco and the Cenomanian Alcântara Formation of Brazil.
