Carcharocles sokolovi is an extinct species or chronospecies of large shark in the family Otodontidae which may represent a transitional chronospecies between Carcharocles auriculatus and Carcharocles angustidens.[1] They differ from the former with a less curved root and finer serrations and from the latter with more prominent and recurved cusps. Due to the subtle differences, it is sometimes lumped into C. auriculatus. It, along with the rest of Carcharocles, is sometimes placed in the genus Otodus. Due to its similarities with other chronospecies, it is difficult to tell exactly when it arose and went extinct. Generally, it is said to span from the late Eocene to early Oligocene. They are best known from the late Eocene localities around Dakhla, Morocco and Fayum, Egypt but are represented in many deposits of contemporary age.[2]
