 "Galeus" fossils, dating to the Burdigalian (20.43–15.97 Ma) and Langhian (15.97–13.65 Ma) stages of the early Miocene, have been recovered from France.The centers of biodiversity for "Galeus" are the North Atlantic (8 species) and the northwestern Pacific (4 species).A few outlying species are found in the South Atlantic ("G. mincaronei" and "G. polli"), Oceania ("G. gracilis" and "G. priapus"), and the Gulf of California ("G. piperatus").
