Abstract

A new specimen of the fossil puffer fish Archaeotetraodon winterbottomi (Tetraodontidae) is described from the lower Oligocene deposits of the Sheshory locality, Ukraine. The specimen reveals a number of characters, some of which are diagnostic and others which were recognized herein for first time, such as the possession of a relatively narrow neurocranium in the supraorbital region, smooth frontals, eight abdominal and nine caudal vertebrae, and long and slender postcleithrum.
