Abstract:
      The Yixian Formation (the Early Cretaceous) of China has yielded a diverse group of early angiosperms, revealing the charm of angiosperms from the formation is far from finishing. Here we report a fossil angiosperm, Nothodichocarpum gen. et sp. nov, with physically connected female parts, male parts, branches, and leaves with pinnate reticulate venation from the Yixian Formation of Liaoning, China. In addition to the previous reports, this report underscores the diversity of angiosperms in the Early Cretaceous Yixian Formation and earlier origin of angiosperms. The morphological variations in the reproductive parts in different stages allow us to infer the development of this early angiosperm. This fossil plant demonstrates a unique character assemblage that sheds new light on the origin and evolution of carpels.
