Anachronistidae is an extinct family of cartilaginous fish, known from the Carboniferous and Permian periods. They are considered to be the oldest known members of Neoselachii (equivalent to Elasmobranchii in its narrow sense), with a close relationship to modern sharks and rays. Known primarily from isolated teeth, these ancient fish were recorded to first exist in Europe during the late Mississippian epoch (Viséan stage).[1][2][3][4] Over time, the genus Cooleyella expanded its range into North America and South America during the Late Carboniferous and continued to exist in the Permian period.[5]
