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