A new disaccate pollen grain from the Triassic of Argentina

Cedripites tectus sp. nov., from the Middle to Late Triassic Rincón Blanco Group of San Juan province, west of Argentina, is a haploxylonoid to slightly dyploxilonoid disaccate pollen grain with a longitudinally oval amb. The corpus is almost rhombic in polar view and trapezium-like in off-polar com...
