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
The following species are recognized as being valid.[1]
Image | Scientific name | Common name | Distribution |

Osteolaemus tetraspis Cope, 1861 | dwarf crocodile, African dwarf crocodile, broad-snouted crocodile, bony crocodile | West and Middle 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]
