Universidad de Zaragoza New bryozoans from the upper ordovician of morocco and their place in the temperate-to-cool water meditterranean province 2016 Access copy available to the general public Unrestricted A new study of the Upper Ordovician bryozoans belonging to the families Aisenvergiidae, Amplexoporidae, Arthrostylidae, Enalloporidae, Halloporidae, Heterotrypidae, Mesotrypidae, Ptilodictyidae, Rhinidictyidae and Trematoporidae from the eastern Anti-Atlas of Morocco is presented here. These bryozoans come from the calcarenitic levels of the Khabt-el-Hajar Formation, upper Katian, where for the first time the orders Fenestrata and Cryptostomata are described in this formation. This fauna inhabited an upper offshore environment and represent high-energy deposits, typical of a shore face environment, as well as storm-induced deposits. A total of 15 species included in 13 genera, 10 of them only identified in the calcarenitic levels of the Khabt-el-Hajar Formation, and two incertae sedis taxa are described. A new species, Trematopora vesiculata, is defined. An update of the Upper Ordovician bryozoan presence/absence database, including the 22 genera described in total in the Khabt-el-Hajar Formation, has been carried out. The augmented database has been analysed with two multivariate statistical techniques: detrended correspondence analysis (DCA) and principal coordinate analysis (PCO), in order to assess the palaeogeographic affinity of this fauna, and the results show that Moroccan bryozoans, in spite of belonging to the fauna developed in the highest latitudes during the upper Katian, have a clear Mediterranean affinity. info:eu-repo/grantAgreement/ES/DGA/E17 info:eu-repo/grantAgreement/ES/MINECO/CGL2012-39471 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 1.175 2016 PALEONTOLOGY 32 / 53 = 0.604 2016 Q3 T2 GEOSCIENCES, MULTIDISCIPLINARY 136 / 188 = 0.723 2016 Q3 T3 0.501 2016 Environmental Science (miscellaneous) 2016 Q2 Earth and Planetary Sciences (miscellaneous) 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Ernst, A.
