Galeorhinus is a genus of houndshark containing one extant species, the widespread but highly threatened school shark ( G. galeus), and several extinct species dating back to the Late Cretaceous (Cenomanian).
The majority of extinct species are known only from fossil teeth, but the Ypresian-aged species G. cuvieri is known from extremely well-preserved full-body specimens from Monte Bolca, Italy. The oldest known species is G. glickmani from the Cenomanian of Russia.
