BALMEIOPSIS, NUEVO NOMBRE GENERICO PARA EL PALINOMORFO INAPERTUROPOLLENITES LIMBATUS BALME, 1957
Abstract
The Lower Cretaceous sediments in Patagonia (Barremian-Albian) contain abundant grains which were referred to lnaperturopollenites limbatus in the literature. Good specimens show that this type has a well developed equatorial thickening and an irregular aperture (hilum) at one pole, Therefore, the species limbatus can no longer be referred to the genus Inaperturopollenites as emended by Potonié (1966). The new name Balmeiopsis is therefore proposed, to in elude this species, which has been found, so far, in Australia, Argentina and Canada. The differences from the genera Coptospora, Cyclusphaera and Araucariacites are established. These grains have been found in Coniferous cones borne on twigs with Brachyphyllum type of foliage; they are possibly close to the Araucariaceae.Downloads
