... is discussed. New Bimerga species were recorded in the Cordobés Formation, the principal potential hydrocarbon source rock in the basin. These species have biostratigraphic value, confirmed by studies from Argentina, Brazil and Bolivia. All stratigraphic records are from the Gondwanan Malvinokaffric Realm...

[1992], with a Malvinokaffric Realm characterised by smooth tetrads and an extra-Malvinokaffric Realm characterised by ornamented tetrads, has to be reconsidered. Clearly...
