Early Cretaceous fern foliage from President Head, Snow Island, Antarctica
Fertile fern foliage described as Lophosoria cupulatus sp. nov. contains the distinctive spore Cyatheacidites annulatus. The fossil foliage is morphologically similar to the Early Cretaceous form-genera Gleichenites and Microphyllopteris, whose time and space distribution in Gondwana matches that of...
