Upper Ordovician Bryozoa from the Montagne de Noire, Southern France
Journal of Systematic Palaeontology
This study focuses on bryozoans from the Upper Ordovician rocks of the Montagne de Noire, southern France and additional material from contemporary rocks of the Carnic Alps. Based on museum collections, 68 bryozoan species were identified with 18 species being new: Ceramoporella grandis sp. nov., Crassalina fungiforme sp. nov., Lichenalia nodata sp. nov., Atactoporella magnopora sp. nov., Dekayia buttleri sp. nov., Stigmatella camica sp. nov., Trematopora gracile sp. nov., Bythopora tenuis sp. nov., Nicholsonella divulgata sp. nov., N. recta sp. nov., Matsutrypa elegantula sp. nov., M. rogeri sp. nov., Nematotrypa punctata sp. nov., Stellatodictya valentinae sp. nov., Ptilodictya feisti sp. nov., Pseudohomera dmitrii sp. nov., Ralfinella elegantula sp. nov. and Moorephylloporina contii sp. nov. Trepostomes are the most abundant and diverse group with 40 of the total 68 species, but cyclostomes, cystoporates and cryptostomes are also present. The age of the fauna is Caradoc to Ashgill, according to the distribution of species and genera. The fauna has palaeogeographical connections to the Upper Ordovician of Wales, Estonia and North America.
