Coccolepis Explained

Coccolepis is an extinct genus of prehistoric marine ray-finned fish in the family Coccolepididae.^[1] Originally including most species within the family, it is now restricted to two species from the Late Jurassic Solnhofen Limestone of Germany.^[2] The holotype of C. bucklandi, designated and described by Louis Agassiz, was thought to be lost but was later rediscovered in Neuchâtel.^[3]

Taxonomy

Coccolepis contains the following species, both from Germany:

• †C. bucklandi Agassiz, 1843
• †C. solnhofensis López-Arbarello & Ebert, 2021

Some species originally referred to Coccolepis were later reallocated to other genera:

• Coccolepis groeberi Bordas, 1943 → Condorlepis groeberi (Bordas, 1943)^[4]
• Coccolepis andrewsi Woodward, 1891 → Morrolepis andrewsi (Woodward, 1891)^[5]
• Coccolepis aniscowitchi Gorizdor-Kulczycka, 1926 → Morrolepis aniscowitchi (Gorizdor-Kulczycka, 1926)^[5]
• Coccolepis macroptera Traquair, 1911 → Barbalepis macroptera (Traquair, 1911)^[6]

The former species “Coccolepis” australis Woodward, 1895 (Late Jurassic of the Talbragar fossil site, Australia) and "Coccolepis" liassica Woodward, 1890 (Early Jurassic of the Jurassic Coast, United Kingdom) are not thought to be members of Coccolepis, but are still of uncertain phylogenetic placement.
