Abstract
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 Variabilitat, die nur mit ausfuhrlichen 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, durfte aber kosmopolitisch in der Psychrosphare (Cyathaxonia-Fazies) des Ober-Famennium anzutreffen sein. Famennian Anthozoa from Morocco. 1. Czarnockia Rozkowska, 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.

期刊介绍:
Fossil Record (FR) is the palaeontological journal of the Museum für Naturkunde Berlin. This journal was founded in 1998 under the name Mitteilungen aus dem Museum für Naturkunde Berlin, Geowissenschaftliche Reihe and appears with two issues each year. Fossil Record publishes original papers in all areas of palaeontology including the taxonomy and systematics of fossil organisms, biostratigraphy, palaeoecology, and evolution. All taxonomic groups are treated, including invertebrates, microfossils, plants, and vertebrates.
