Abstract

The Devonian was a critical period in the global evolution of brachiopods, during which the phylum reached its maximum diversity in the Emsian and experienced a significant decline during the Frasnian–Famennian, second only to the mass extinction of the Late Permian. The brachiopod fauna of the Manacapuru Formation (Lochkovian) was unknown until 2011, when a significant number of Rhynchonelliformea and Linguliformea samples were recovered during paleontological salvage at the Belo Monte hydroelectric plant in Vitória do Xingu, Pará, Brazil. This study aims to identify the Orthotetida from this salvage. The taxonomic study of the brachiopods from the Manacapuru Formation (Lochkovian) led to the recognition of a new species, Schellwienella amazonensis n. sp., Family Pulsiidae Cooper and Grante, 1974. Schellwienella amazonensis n. sp. and Schellwienella marcidula Amsden, 1958 originally described to the Bois d’Arc Formation (Lochkovian), USA are the oldest records of the genus. The genus Schellwienella was present throughout all stages of the Devonian, primarily in the Gondwana siliciclastic marine environments, transiting between temperate and polar latitudes, and disappeared in the Viséan (early Carboniferous) under warmer waters and carbonate platform conditions typical of low-latitude regions.

期刊介绍： Papers must have a regional appeal and should present work of more than local significance. Research papers dealing with the regional geology of South American cratons and mobile belts, within the following research fields: -Economic geology, metallogenesis and hydrocarbon genesis and reservoirs. -Geophysics, geochemistry, volcanology, igneous and metamorphic petrology. -Tectonics, neo- and seismotectonics and geodynamic modeling. -Geomorphology, geological hazards, environmental geology, climate change in America and Antarctica, and soil research. -Stratigraphy, sedimentology, structure and basin evolution. -Paleontology, paleoecology, paleoclimatology and Quaternary geology. New developments in already established regional projects and new initiatives dealing with the geology of the continent will be summarized and presented on a regular basis. Short notes, discussions, book reviews and conference and workshop reports will also be included when relevant.
