Libys is a genus of coelacanth fish in the family of Latimeriidae. Species of Libys lived during the Lower-Upper Jurassic period (Toarcian - Tithonian, about 183 to 145 million years ago).
Description
[edit | edit source]Libys had an exceptionally squat body, especially when compared to other coelacanths of the same period as Undina and Holophagus. Libys could reach 60 centimeters in length and was therefore a medium-sized coelacanth, with a short and high skull. The pectoral fins were quite long, while the tail was remarkably short and high.[1]
Distribution
[edit | edit source]Fossils of these fishes have been found in Germany, in the famous deposits of Solnhofen.
Species
[edit | edit source]- Libys superbus Reis, 1888
- Libys polypterus
- Libys callolepis[2]
The genus Libys was erected in 1842 by Muenster. The species Libys polypterus was then established as the type species, on the basis of fragmentary remains. A second species, L. superbus, was described on the basis of complete large specimens, but most authors treat both as one species.
