Abstract

Smooth and cingulate trilete and monolete disperse spores from the Punta del Barco Formation, Lower Cretaceous of Santa Cruz Province are being described in this paper. The trilete spores belong to the genera Biretisporites, Deltoidospora, Todisporites, Cyathidites, Densoisporites, Foraminisporis, Contignisporites, Laevigatosporites and Reticulosporis. The last genus is mentioned for the first time in Argentina, and is one of the oldest known records. Some of these taxa represent vegetal groups no reported for this taphoflora, enlarging therefore its previous knowledge.
