COVER An early fossil flower, Archaefructus sinensis sp. nov., from the lower Yixian Formation (Upper Jurassic/Lower Cretaceous), Liaoning, China. Morphological and molecular analyses suggest that Archaefructus is a basal angiosperm. Thin stems, dissected leaves, and associated fish (Lycoptera davidi Sauvage) indicate that these were aquatic flowering plants. 899 [Photo: David Dilcher, Ge Sun, Qiang Ji]
