Gyrolepis is an extinct genus of prehistoric marine ray-finned fish from the Middle-Late Triassic epochs in what is now Europe. It is known both from complete specimens and isolated skeletal elements, such as scales or teeth.
Taxonomy The following species are placed in this genus:
G. agassizi (Münster, 1835) - Anisian of Germany (Muschelkalk), Ladinian of France G. albertii Agassiz, 1835 (type species) - Anisian of the Netherlands (Vossenveld Formation of Muschelkalk), Poland (Wellenkalk Formation), late Anisian/early Ladinian of Germany (Muschelkalk), Norian of Austria (Seefelder Formation) & Belgium (Grès de Mortinsart Formation), Rhaetian of England (Westbury Formation) and France, potentially Anisian of Spain (Muschelkalk) G. angulisulcatus Oertle, 1927 - Ladinian of Germany (Muschelkalk) G. ornatus Giebel in Dames, 1888 - Anisian of Germany (Muschelkalk) G. quenstedti Dames, 1888 - Ladinian of Germany (Muschelkalk) G. parcisquamosus Oertle, 1927 - Ladinian of Germany (Muschelkalk) G. pompeckji Oertle, 1927 - Ladinian of Germany (Muschelkalk) G. tenuidentatus Oertle, 1928 - late Anisian/early Ladinian of Germany (Muschelkalk) An indeterminate species is known from the Besano Formation of Italy & Switzerland. A potential species is also known from the Rhaetian of China.
Distribution Gyrolepis fossils have been found across much of the Northern Hemisphere, but the genus was by far most common in Europe. G. albertii, the type species of the genus, is a ubiquitous component of Rhaetian biotas in Europe.
