Otodus (Carcharocles) sokolowi

Searched as Otodus sokolovi. The Paleobiology Database treats Otodus (Carcharocles) sokolowi as the accepted name.

Otodus sokolovi is an extinct species or chronospecies of large shark in the family Otodontidae which may represent a transitional chronospecies between Otodus auriculatus and Otodus angustidens. 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 O. auriculatus. It, along with the rest of Otodus, is sometimes placed in the genus Carcharocles. 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. It measured at least 6 metres (20 ft) long.

59 occurrences of Otodus (Carcharocles) sokolowi on record, most of them in the Eocene. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

59 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.
