The Yixian Formation in northeast China is worldwide famous for its fossils of early angiosperms, which play a key role in the study of early evolution of angiosperms. Despite all efforts, the morphological gap between angiosperms and gymnosperms remain as conspicuous as ever, due to lack of a fossil plant intermediate between angiosperms and gymnosperms. It is well-known that angiosperms are distinguished from gymnosperms, which have naked ovules, by their enclosed ovules. A plant intermediate between angiosperms and gymnosperms should have both enclosed as well as naked ovules in the same plant. Although some extant angiosperms may have their ovules not fully enclosed and some extant gymnosperms have their seeds enclosed, none of fossil or living plants has its ovules naked and enclosed in the same plant hitherto. However, Darwinism does expect such a chimeric existence. Here I report such a long-expected plant, Lingyuanfructus hibrida gen. et sp. nov, from the Yixian Formation (Lower Cretaceous). The unique feature of Lingyuanfructus is that, in a single fossil, the ovules are both naked and enclosed, exactly the expected chimera filling the huge morphological gap between angiosperms and gymnosperms.
