The genus Gonioclymenia (Ammonoidea; Late Devonian) in the Anti-Atlas of Morocco

The Famennian (Late Devonian) ammonoid genus Gonioclymenia is revised based on material from the Anti-Atlas of Morocco. Six species are separated, five of which are newly described here: Gonioclymenia wendti n. sp., G. ali n. sp., G. spiniger n. sp., G. ebbighauseni n. sp., and G. inornata n. sp. The morphology of these species shows that they are probably endemic to the North Gondwana Continental margin and are separated from the occurrences of Gonioclymenia in Central Europe and the South Urals.
