Fig. 17 in Kasimovian (late Pennsylvanian) cornute rugose corals from Egypt: taxonomy, facies and palaeogeography of a cool-water fauna from northern Gondwana

Fig. 17 Palaeobiogeographic relations of the cyathaxonid coral fauna of the Aheimer Formation (asterisk) showing its rooting in the western Palaeotethys (red dots) and the strong relations to the cool-water Cordilleran–Arctic–Uralian realm (yellow dots). The fauna is a precursor of the Lower Permian cyathaxonid cool-water fauna of the eastern Cimmerian peri-Gondwana terranes (E´pGT). Base map from Abd-Elhameed et al. (2021) as modified from Kiessling et al. (1999)
