Galeorhinus Tenius
''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 ...

Physogaleus
''Physogaleus'' is an extinct genus of small requiem shark that lived from the Late Paleocene to Miocene epochs. Description ''Physogaleus'' is only known from fossil teeth and isolated vertebra. The teeth are similar to those of the modern Tiger shark, but are smaller, with a more central cusp that projects further from the base of the tooth. The species of ''Physogaleus'' were originally described as belonging to the same genus as the modern Tiger shark, ''Galeocerdo ''Galeocerdo'' is a genus of ground shark. Only a single species, ''G. cuvier'', the tiger shark, is extant. The earliest fossils date back to the early Eocene epoch, (Ypresian), around 56–47.8 Million years ago. While historically considered a ...''. Recognition of numerous differences in dental anatomy of each of these species compared to other species of ''Galeocerdo'' lead researchers to establish the genus ''Physogaleus'' to include taxa that were more morphologically similar to one another than they were ...

Arambourg
Camille Arambourg (February 3, 1885 – November 19, 1969) was a French vertebrate paleontologist. He conducted extensive field work in North Africa. In the 1950s, he argued against the prevailing model of Neanderthals as brutish and simian. During World War 1, he was in Military service. After that he was a professor of Geology at the Institut Agricole d'Alger, and after that a professor of Paleontology at Muséum National d'Histoire Naturelle in Paris, where he succeeded his teacher Marcellin Boule.
