Eosaurichthys is an extinct genus of saurichthyid ray-finned fish that lived during the late Permian epoch (Changhsingian age) in what is now China .[1]
Taxonomy
Eosaurichthys is often treated as a subgenus of Saurichthys rather than a genus, with its type species referred to as Saurichthys (Eosaurichthys) chaoi.[2] The Early Triassic species Saurichthys madagascariensis has been referred to this subgenus as Saurichthys (Eoaurichthys) madagascariensis.[3][4]
Appearance
Eosaurichthys closely resembles its daughter genus, Saurichthys, in both form and morphology. Its body is fully covered by scales, while in Saurichthys the scale cover is reduced.[2][5]
