Osteolaemus is a genus of crocodiles.[1][2][3] They are small, secretive crocodiles that occur in wetlands of West and Middle Africa. They are commonly known as the African dwarf crocodiles.[2] Unlike other crocodiles, Osteolaemus are strictly nocturnal.[3]

Species[edit]

The following species are recognized as being valid.[1]

Image Scientific name Common name Distribution
Osteolaemus osborni Schmidt, 1919 Congo dwarf crocodile Congo River basin of Central Africa
Osteolaemus tetraspis Cope, 1861 dwarf crocodile, African dwarf crocodile, broad-snouted crocodile, bony crocodile West Africa and Ogooué River basin of Central Africa
Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Osteolaemus.

Molecular data suggest that Osteolaemus tetraspis consists of two lineages that would warrant recognition as distinct species.[2]
