摘要

The clasper of a xenacanth shark, Orthacanthus kounoviensis, is described and compared with that of other xenacanths. The pelvic fin of male xenacanth sharks shows generic and familiar differences. The palaeoecology of the Carboniferous-Lower Permian locality Buxieres-les-Mines is compared with other basins in Central France, Spain, Saar-Nahe, Thuringia, Bohemia and the USA. A marine influence is postulated based on faunal and physiological comparison.
