Paredes R., Comas-Rengifo M. J., Duarte L.V., Goy A. (2013) Braquiópodes do Sinemuriano superior da região de S. Pedro de Moel e de Peniche (Bacia Lusitânica, Portugal) // Comunicações Geológicas, 100, Especial I, 29-35

http://www.lneg.pt/downloa....nal.pdf

The stratigraphical distribution of Upper Sinemurian brachiopods at S. Pedro de Moel and Peniche (Lusitanian Basin) is presented here. They are represented by 9 families, 11 genera and 21 recognized species, spanning from the Oxynotum to the lower part of Aplanatum subchronozones at S. Pedro de Moel and from the upper part of Aplanatum to lower part of Taylori subchronozones in the Peniche area. The most common families are Rhynchonellidae (39%), Tetrarhynchiidae (28%) and Zeilleriidae (16%). The highest abundance and diversity of brachiopods is recognized in the Oxynotum Subchronozone at S. Pedro de Moel. A rapid decrease in brachiopods is observed until the lower part of the Aplanatum Subchronozone, interpreted as the result of specific local conditions, most probably related to a deepening episode and/or oxygen depleted conditions. Shallower water conditions are inferred by the
represented associations at Peniche. Most of the recorded taxa are related with the NW European Province.
