Hooked-Horn Sculpins (Pisces: Cottidae, Artediellinae) from the Miocene of Sakhalin Island, Russia

Аннотация

Two new species of the recent genera of hooked-horn sculpins (Pisces, Cottidae, Artediellinae) are described from Miocene deposits (Serravalian–Tortonian) of the Agnevo Formation, Sakhalin Island, Russia. This is the first record of fossil skeletal remains of members of the subfamily Artediellinae. The Miocene hooked-horn sculpins are similar to modern fishes of this subfamily in the main countable characters and body proportions, but differ in a number 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.
