Oligocene-Early Miocene macrofossils of parts of a fertile frond are assigned to the extant South American species Lophosoria quadripinnata (Gmel.)C.Chr. These macrofossils bear the dispersed spore species Cyatheacidites annulatus Cookson ex Potonié. This species has an extensive recorded history in...
