| An interesting brachiopod fauna from Namurian (Marsdenian?) deposits — provisionally named the Meré beds herein — is described. The fauna contains seven new species: Drahanorhynchus cantabricus, Anopliopsis? parva, Caenanoplia martinezi, Tornquistia scutiformis, Aseptella asturica, Kitakamithyris merensis, and Plicotorynifer lamellosus; and one new genus: Aseptella with the type species A. asturica. The material of a new productellid and a new ambocoeliid was too poor to give them formal names. The special character of this fauna — only a much older fauna from the Chappel Limestone of Texas (U.S.A.) being closely comparable — indicates special environmental conditions: presumably a soft, muddy bottom. The brachiopod fauna indicates a Namurian, probably... |

| The analysis of early Kasimovian (Pennsylvanian) brachiopod assemblages from two fossiliferous localities of the Las Llacerias Formation (Ándara Massif, Picos de Europa, northern Spain) improve our knowledge of this fossil group in the Cantabrian Zone. At the Morra de Lechugales Peak (locality 1), marlstones and bioclastic limestones, accumulated in a low energy, subtidal, aphotic setting, characterize a soft muddy sea-floor affected by periodic intense bottom currents and provide a rich assemblage of brachiopods together with other macrofossils. Brachiopod specimens are characterized by their small size (<10 mm) and belong to 38 different taxa. The fossiliferous dark marly limestones at the Castillo del Grajal (locality 2) record a very shallow water,... |
