Abstract: This is the first extensive study of a freshwater fish fauna from the Pliocene site of Koro-Toro (Chad), aged 3.58±0.27Ma. The assemblage includes an abafish (Mormyriformes, Gymnarchidae: Gymnarchus), a tigerfish (Characiformes, Alestidae: Hydrocynus), six different catfishes (Siluriformes, Ariidae: Carlarius; Bagridae: Bagrus; Claroteidae: Clarotes and Auchenoglanis; Mochokidae: Synodontis; Clariidae: Clarias or Heterobranchus), perciform fishes (Perciformes, Latidae: Lates sp. cf. niloticus, and Cichlidae indet.), and a pufferfish (Tetraodontidormes, Tetraodontidae: Tetraodon). The diversity is relatively low when compared with other Chadian Neogene sites. This is probably mostly explained by the wind erosion of the outcrops being responsible for the lack of minute remains. However, we recognize that the aquatic environment recorded corresponds to open waters. [Copyright &y& Elsevier]
