The Devonian eodevonariids (Chonetidina, Brachiopoda) from the Taoudeni and South of Hoggar basins, Sahara.

The study of Devonian chonetoidean brachiopods from the Taoudeni and South Hoggar basins, in Mali and Niger, South of the Reguibat-Hoggar shield, allo ws the description of new eodevonariid species: Lomaella amziensis nov. sp. (Tassilis Oua-n-Ahaggar, south Hoggar Basin), Eodevonaria taoudeniensis no v. sp. and Loreleiella sp. (Taoudeni Basin). The occurrence of the genus Lo maella in NW Africa, only known hitherto from South America, allows analysi ng the hypothetical connecting migratory routes between both regions situat ed on the western part of the Gondwana palaeocontinent during the late Emsi an. The phylogenetic relationships of Lomaella and Eodevonaria with the SW European genera Davoustia-Renaudia-Loreleiella are discussed. (C) 2001 Edit ions scientifiques et medicales Elsevier SAS.
