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] .
