Asiatoceratodus is an extinct genus of lungfish which lived during the Middle-Late Triassic, Jurassic and Cretaceous periods in what is now Asia (Kyrgyzstan), Africa (Ethiopia, Niger, Algeria, Morocco) and South America (Uruguay and Brazil).

Species

edit

Asiatoceratodus sharovi

edit

Complete skeletons of Asiatoceratodus sharovi first described by Vorobyeva (1967) from the Middle-Late Triassic deposits of Fergana valley in Kyrgyzstan.[1][2] This species is characterizes by toothed plates with 4 to 5 crests.[1]

Asiaticeratodus tiguidiensis

edit

Another species originally was described from the Late Jurassic site of Algeria as Ceratodus tiguidiensis[3] Later, C. tiguidiensis was assigned to Arganodus by M. Martin (1984)[4] and reassigned by Kemp (1998) to the genus Asiatoceratodus.[5] Despite this, some authors uses Arganodus tiguidiensis in their articles.[6] A. tiguidiensis was also found in the Late Jurassic (Kimmeridgian) Tacuarembo Formation of Uruguay,[7] the northwestern Ethiopian plateau of latest Jurassic (Tithonian) age,[8] the Cretaceous Elrhaz Formation of Niger,[9] the Early Late Cretaceous assemblage of Southeastern Morocco[6] and the Cenomanian Alcântara Formation of Brazil.
