Galeocerdo

Tiger shark

Galeocerdo, the tiger shark, has been around since the Eocene; the fossil species G. aduncus and G. cuvier (the living one) leave small, notched, coarsely serrated teeth in Miocene–Pliocene beds from Florida to Maryland and in Morocco. Tiger shark teeth are cheap, distinctive and a good teaching fossil. Physogaleus, an older relative, is often mislabelled Galeocerdo.
