Vertebrate microremains have been prepared by acid leaching from oolitic limestone beds at the Devonian/Carboniferous boundary stratotype of La Serre, southeastern Montagne Noire, southern France. They all come from the lowermost Carboniferous beds 89 to 99, i.e., the sulcata and kockeli-dentilineatus conodont zones. Most remains are of elasmobranchs: Symmorium sp., Stethacanthus? sp., Ctenacanthidae gen. et sp. indet., Phoebodus cf. P. australiensis, Thrinacodus ferox, Protacrodus cf. P. vetustus, P. sp., Elasmobranchii gen. et sp. indet. types A-C; with a few actinopterygian teeth. The assemblage correlates well with other Upper Devonian-Lower Carboniferous localities from the USA, western and eastern Europe, southeast Asia, China, Morocco and Australia.
