The Lower Miocene (MN 4) locality of Dolnice (West Czechoslovakia) has yielded remains of about 12 ophidian taxa: Scolecophidia indet., Bransateryx septentrionalis, n.sp., cf. Gongylophis sp. (Boidae), Palaeonatrix lehmani, Neonatrix nova, n.sp., Texasophis bohemiacus, n.sp., Coluber dolnicensis, n.sp., three different unidentified colubrine snakes (Colubridae), Vipera platys-pondyla, n.sp., and Vipera antiqua, n.sp. (Viperidae). Several of the above snake genera are well known from other Miocene sites in West Europe and North America (Bransateryx, Neonatrix, Texasophis), while others represent recent genera of more isolated occurrence (Gongylophis, Vipera of the “Oriental vipers” group).
