Abstract

Despite increasing claims of pre-Cretaceous angiosperms, whether there really are angiosperms in the Jurassic is apparently still an open question for many people before further evidence is available. This question can only be answered by studying more Jurassic plant fossils. Here we report a fossil angiosperm, gen. et sp. nov, from the Middle Jurassic of Inner Mongolia, China. The plant includes connected stem, leaves, flowers, aggregate fruits, fruitlets, and seeds within fruitlets. The leaves are helically arranged along the curving stem, linear in shape, with 5-6 parallel veins. The aggregate fruit is pedicellate, composed of over 20 carpels/fruitlets helically arranged. Each fruitlet encloses a seed. The reproductive organs in various stages are found in the same plant, allowing us to understand the development of . The occurrence of in the Middle Jurassic re-confirms the Jurassic history for angiosperms that has been suggested by other independent research and adds to the on-going study on the early evolution of angiosperms.

摘要

尽管关于白垩纪之前被子植物的说法越来越多,但在有更多证据之前,侏罗纪是否真的存在被子植物对许多人来说显然仍是一个悬而未决的问题。这个问题只能通过研究更多的侏罗纪植物化石来回答。在此,我们报道了一种来自中国内蒙古中侏罗世的化石被子植物,新属新种。该植物包括相连的茎、叶、花、聚合果、小果以及小果内的种子。叶子沿弯曲的茎呈螺旋状排列,形状为线形,有5 - 6条平行脉。聚合果具柄,由20多个螺旋状排列的心皮/小果组成。每个小果内包有一粒种子。在同一植株上发现了处于不同阶段的生殖器官,这使我们能够了解……的发育过程。该中侏罗世植物的出现再次证实了其他独立研究所提出的被子植物的侏罗纪历史,并为正在进行的被子植物早期演化研究增添了内容。
