Pholidophorus

 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 40 centimetres (16 in) 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.
