''Pholidophorus'' is an extinct genus of teleost fish from the Triassic and Jurassic periods of Africa, Europe, and South America. ''Pholidophorus'' was a herring-like fish about long, although it was not closely related to modern herring. Like them, however, it had a single dorsal fin, a symmetrical tail, and an anal fin placed towards the rear of the body. It had large eyes and was probably a fast-swimming predator, hunting planktonic crustaceans and smaller fish. A very early teleost, ''Pholidophoris'' had many primitive characteristics such as ganoid scales and a spine that was partially composed of cartilage, rather than bone.〔 == A contrary view == According to T.S. Kemp, "a single species of fish from the Jurassic, ''Pholidophorus bechii'', is thought to be the sister-group" of all fossil and living teleosts.〔Kemp T.S. 1999. ''Fossils and evolution''.
