Cycloptychius is an extinct genus of prehistoric freshwater & marine ray-finned fish that existed throughout much of the Carboniferous period in Eurasia, and possibly into the Early Permian in South Africa.[2][1] It was a member of the Rhadinichthyidae, a family of basal ray-finned fish that was formerly placed in the now-paraphyletic order Palaeonisciformes.[3][4]
It contains the following species:[5]
- †C. bidens Matveeva, 1958 - Early Carboniferous (Tournaisian) of Krasnoyarsk Krai, Russia (Os’kin Formation)
- †C. carbonarius Young, 1866 - Late Carboniferous (Moscovian) of England (North Staffordshire Coalfield)
- †C. concentricus Traquair, 1881 - Early Carboniferous (Viséan) of Scotland (Glencartholm Volcanic Beds)
- ?†C. loocki Evans, 2005 - Early Permian (Artinskian) of South Africa (Whitehill Formation)[6]
