Abstract

Lower Winds or B Subzone Mississippian sediments in the Western part of the Minas sub-basin were sampled faunally and lithologically. In particular the carbonate units represented , which were deposited in transgressive-regressive seas under arid climatic conditions, were discriminated on the basis of their contained productids . A new species of Diaphragmus, two new species of Ovatia and several varieties of Q. l yelli ( de Verneuil) are described . Phylogenetic relationships based on morphological features are postulated. Ecological data is interpreted fr om biotic relationships and from a megascopic and microscopic study of each stratigraphic unit . The productids are not apparently narrowly restricted environmentally and occurred from low intertidal to low sublittoral.
