Short summary
The teleosts (e.g., herrings, trouts) comprise the largest group of living fishes today. The aim of the present study is to investigate and describe a new species of the primitive teleost Tharsis from the Late Jurassic. Tharsis is currently known by one species, Tharsis dubious, which is one of the most common fish in the Solnfohen limestone, Bavaria, Germany. A new species, Tharsis elleri, is described and assigned to the family Ascalaboidae within the new order Ascalaboidiformes.
