Tegeolepis is an extinct genus of ray-finned fish, whose fossils have been found in the Upper Cleveland Shales in what is now the United States[1]. T. clarki is the type and only species within this genus[1]. It represents one of the first large piscivorous ray-finned fishes and exhibited robust pectoral fins and a fusiform body[1]. A close relative of Tegeolepis, named Austelliscus ferox has been found in Middle Devonian strata from Southern Brazil[2]. The phylogenetic relationships of Tegeolepis remain uncertain, but evidence indicates it would be placed outside the crown group of ray-finned fishes[1][2][3].
