Hooked-Horn Sculpins (Pisces: Cottidae, Artediellinae) from the Mioceneof the Sakhalin Island, Russia
Two new species of the modern genera of hooked-horn sculpins (Pisces, Cottidae, Artediellinae) are described from the deposits of the Miocene (Serravalian-Tortonian) Agnevo Formation, Sakhalin Island, Russia. These are the first record of fossil skeletal remains of representatives of subfamily Artediellinae. Miocene hooked-horn sculpins are similar to recent fishes of this subfamily in the main counts and body proportions, but differ in the row of primitive features, such as the presence of skin spinules covering the body up to the caudal fin base, and the presence of spines on the posterior edge of the lateral line scales.
