Galeorhinus
''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 Early Eocene-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.

School Shark
The school shark (''Galeorhinus galeus'') is a houndshark of the family Triakidae, and the only living member of the genus '' Galeorhinus''. Common names also include tope, tope shark, snapper shark, and soupfin shark. It is found worldwide in temperate seas at depths down to about . It can grow to nearly long. It feeds both in midwater and near the seabed, and its reproduction is ovoviviparous. This shark is caught in fisheries for its flesh, its fins, and its liver, which has a very high vitamin A content. The IUCN has classified this species as critically endangered in its Red List of Threatened Species. Taxonomy The school shark is the only extant member of '' Galeorhinus'', an ancient genus that dates to at least the Early Eocene, when the very similar species '' G. cuvieri'' is known, and likely as far back as the mid-Cretaceous. Fossil teeth of the modern school shark date as far back as the mid-late Eocene, where they are known from the Castle Hayne Formation of N ...
