Pennsylvanian (Carboniferous) brachiopods from the Itaituba Formation of the Amazon Basin, Brazil

A new brachiopod fauna is described from the lower Itaituba Formation at the Caima Quarry 2 section in the Itaituba area, Amazon Basin, Brazil. The <i>Amazonoproductus amazonensis</i>-<i>Anthracospirifer oliveirai </i>Assemblage is proposed for this fauna, which is considered early Pennsylvanian (Morrowan) as constrained by associated conodont and fusulinacean faunas. Nine brachiopod taxa are described herein, including <i>Amazonoproductus</i> <i>amazonensis </i>gen. et sp. nov., and <i>Buxtonioides itaitubensis </i>sp. nov. and <i>Linoproductus caima </i>sp. nov. The new tribe Marginovatini of the Linoproductoidea (the Productida) is also proposed.<br />
