Fig. 12. Distribution areas of different Lissodus species in Europe. A. Latest Carboniferous/earliest Permian (Stephanian C): Lissodus lacustris is the most common species; Lissodus lopezae is restricted to Central Spain, and Lissodus cf. zideki shows a migration into the eastern Saar−Nahe Basin documenting the existence of migration possibilities between the single basins, other routes to the northwestern Rheic Ocean and to the southern Sardinia are just assumed. B. Early Permian (Asselian%Sakmarian): Lissodus cf. lacustris is a relic of Lissodus lacustris; Lissodus sp. (NM), Lissodus sp., and Lissodus sardiniensis sp. nov. are considered to be endemic relicts of L. cf. zideki in its former occurrence area; and the appearance of L. zideki in the late Early Permian of North America is also regarded as the result of NW migration.
