About this book

Language: Two German and one French contribution with trilingual abstracts in English, French, and German

Contains the following three contributions:

Christian Franke: Marine Fauna der Wiltz-Schichten (Ober-Emsium, Unter-Devon) der Mulde von Wiltz und der Daleider Mulden-Gruppe (Luxemburg, Deutschland): Teil 1
A multitude of new finds permit a fundamental revision of the fossil contents of he Wiltz layers. For this purpose, approx. 5700 proofs of finds were evaluated. Due to the numerous finds, the study will be published in several parts. It turns out that the species-diversity is very much greater than assumed to date. The presence of many of genera and species known from other sedimentation areas have now been proved for the Wiltz-layers in the Wiltz-basin and Daleiden Synclinal Group This publication includes plant fossils, Rhaphidopora sp. cf. Rhaphidopora lonsdalei, Cornulites sp. and Pterygotoidea fam. et gen. et sp. indet. The trilobite Leonaspis grafi n. sp. is redescribed.

Finally, the area examined can be defined as an extensive long-lived deposit region of a shallow water situation extending from close to and far from the coast of he Ardenno-Rhenish continental shelf with multifold faunistic correspondences to other regions in the Variscan sea during the upper Emsian.

Peter Müller & Mirko Alberti: Burmeisterella vixarmata aus der Klerf-Formation in Nord-Luxemburg (Trilobita, oberes Unter-Devon)
Newly discovered material from the quarry of Merkholtz (W of Kautenbach, Luxembourg) gives rise to a new reconstruction of Burmeisterella vixarmata Wenndorf, 1990. Furthermore, indications about its range of variation and its mould process are provided. An association of Burmeisterella vixarmata Wenndorf, 1990 with Burmeisterella armata (Burmeister, 1843) is considered improbable.

Yves Plusquellec & Christian Franke: Présence précoce du genre Kerforneidictyum représenté par K. oeslingensis n. sp. (Cnidaria, Tabulata) dans l'Emsien inférieur du Grand-Duché de Luxembourg
A new species of Kerforneidictyum, K. oeslingensis n. sp., is described. It is mainly characterized by the following features: apical angle reaching up to 160°, deep calices with numerous small spines roughly of the same size, setted in two rows or scattered on septal ridges which are wider than the interseptal furrows, no obvious cardinal ridge, tabulae scarce or missing. The species has been collected in the lowermost Emsian of the Givonne-Eislek Anticlinorium in Luxembourg. It is 1) the first record of the genus in the Devonian of Luxembourg and 2) in the autochtonous part (S.E. Laurussia) of the Ardenno-Rhenish Mountains and 3) very likely the first – or one of the two first – representative of the genus taking into account Gondwana and Laurussia.
