Abstract. Aus Cephalopoda-Kalken der mittleren/oberen Clymenia-Stufe (Niveau mit Gonioclymenia) des Tafilalt im Anti-Atlas ist Czarnockia maroccana n. sp. beschrieben. Die Kollektion von 7 Polyparen zeigt eine erhebliche innerartliche Variabilität, die nur mit ausführlichen Schliffserien aller subtabularen und calicularen Regionen erfassbar wird. Das seltene, bisher allein aus der Wocklumeria-Stufe des Heiligkreuz-Gebirges in Polen bekannte Petraiidae-Genus – Endglied einer phylogenetischen Reihe Neaxon → Petraia → Famennelasma → Czarnockia – ist erstmals in einem weitern Verbreitungsareal nachgewiesen, dürfte aber kosmopolitisch in der Psychrosphäre (Cyathaxonia-Fazies) des Ober-Famennium anzutreffen sein.

Famennian Anthozoa from Morocco. 1. Czarnockia Różkowska, 1969 (Rugosa)

The new species Czarnockia maroccana is described from cephalopod limestones of the middle/upper Clymenia genozone (level with Gonioclymenia) in the Tafilalt district of the Anti Atlas region. The small collection of seven syntypes demonstrates a surprising intraspecific variation visible only after intensive serial sectioning of all subtabular and calicular parts of the skeleton. This is the first record of the rare genus from a second area outside the type occurrence in the Wocklumeria genozone of the Polish Holy Cross Mountains. As a member of the phyletic line Neaxon → Petraia → Famennelasma → Czarnockia, the taxon should be found cosmopolitically in the psychrospheric Cyathaxonia facies of Upper Famennian times.
