The revision of some Odontaspididae species from the Paleocene and the Eocene of the North sea Basin has clarified the generic status of some of them and to precise their dental morphologies. A species from the Lutetian of Belgium, Carcharias sp., can be considered as the first representative of the lineage leading to the Recent species C. taurus. Three new genera are described: Brachycarcharias nov. gen. (Lutetian of Belgium), Orpodon nov. gen. (Selandian of Belgium) and Sylvestrilamia nov. gen. (Ypresian of England). The validity of the genus Hypotodus is confirmed and it is recommended that the poorly defined species hopei is abandoned in favour of the species verticalis in order to avoid confusion
