Karpinskiprion is an extinct genus of cartilaginous fish from the Late Carboniferous of what is now Russia. It contains one species, Karpinskiprion ivanovi, which was originally described as a species of the genus Helicoprion and later as Campyloprion.
Three specimens of Karpinskiprion have been discovered from the Gzhelian-stage Kosherovo Formation of Moscow Oblast, Russia; one of which is the holotype fragment, another is a proportionally larger fragment, another is a more complete pair of fragments. An even more complete specimen was discovered from either the Kurakino Formation or the Parubino Formation of Volograd Oblast, Russia. These sites are approximately the same age as the Kosherovo Formation, and likely also date to the Gzhelian stage. The described material of the genus is in the collection of the Paleontological Institute, Russian Academy of Sciences. Additional fragmentary specimens that may belong to the genus from the late Pennsylvanian are also known; these are in the collection of the Universe History Museum in Dedovsk, Moscow Oblast.[1]
The genus name honors Alexander Karpinsky, who first described the type species in 1924.[1][2]
