Paratirolites is a genus of latest Permian and earliest Triassic ceratites from Armenia, Azerbaijan, Afghanistan, China and Iran with distinct ribs, prominent ventro-lateral tubercles, and a broadly arched venter. The suture is ceratitic with a large ventral saddle.[1][2][3] Ceratites are ammonoid cephalopods that lived during the Late Permian and Triassic.
Paratirolites is included in the Xenodiscoidean family Dzhulfitidae along with Abichites and Dzhulfites.[4] Previously it was included in the Stephanitidae,[1] a family belonging to the Ceratitoidea.
Species of Paratirolites have also been found in the Upper Permian of Azerbaijan, China, Thailand and Japan, and in the Triassic of Azerbaijan and Afghanistan.[4]
