Norberto Malumian

Abstract


Province subsurface. Foraminifers from Oligocene and Miocene sediments of the Buenos Aires Province subsurface, mentioned in Malumián (1970), are treated systematically. A later finding: Globigerina brevis Jenkins, indicates the ocurrence of Lower Oligocene in the Colorado Basin, and confirms a relation of planktonic foraminifers from Argentine with those of New Zealand-South Australia. All together, 96 specia and forms, distributed in 49 genera, are considered, and a new species: Fissurina coloradoensis is described.
