Galeocerdo is a genus of ground shark. Only a single species, G. cuvier, the tiger shark is extant[1] The earliest fossils date back to the Eocene epoch.[2] While historically considered a member of the requirem shark family Carcharhinidae. It is currently considered to be the only member of the family Galeocerdonidae.[3] While this genus was historically considered diverse, including 21 extinct species, morphometric analysis conducted in 2021 suggested that the diversity of the genus included only 5 extinct species (including the Eocene †G. clarkensis and †G. eaglesomei, Oligocene-late Miocene †G. aduncus, Miocene †G. mayumbensis, and Pliocene †G. capellinii) much lower than previously assumed. The oldest fossils of the extant G. cuvier date to the middle Miocene.[2]
Species historically considered valid in the genus Galeocerdo include:[4]

Galeocerdo is een monotypisch geslacht van de familie van requiemhaaien (Carcharhinidae) en kent slechts 1 soort. Fossielen zijn bekend vanaf het Eoceen.[2]
De tanden van deze 500 cm lange haai bestaan uit kronen met fijn gezaagde hoofdspitsen. Het snijvlak is grover gezaagd. Aan de basis bevindt zich een ondiep voedingskanaal en meerdere vaatopeningen.
Deze haai zwemt voornamelijk rond in kustwateren.
Fossielen van deze vis werden overal ter wereld gevonden.
