The oldest lamprophiid (Serpentes, Caenophidia) fossil from the late Oligocene Rukwa Rift Basin, Tanzania and the origins of African snake diversity Geobios (IF 1.197) Pub Date : 2020-12-02 Jacob A. McCartney; Sierra N. Bouchard; Josephine A. Reinhardt; Eric M. Roberts; Patrick M. O'Connor; Cassy Mtelela; Nancy J. Stevens
Extant snake faunas have their origins in the mid-Cenozoic, when colubroids replaced booid-grade snakes as the dominant species. Based on fossils from North America and Europe, the timing of this faunal changeover is thought to have occurred in the early Neogene, after a period of global cooling opened environments suitable for more active predators. However, new fossils from the late Oligocene of
