Abstract
AbstractThe Jurassic is an important period for the origin of angiosperms. Several reproductive organs have been excavated from the Jurassic strata in western Liaoning and Inner Mongolia, China. Schmeissneria, Xingxueanthus and Solaranthus are three female or bisexual organs of plants found in the Middle Jurassic in China and the Early Jurassic in Europe. All of them demonstrate the existence of enclosed ovule in the organ, satisfying the criterion for angiosperms. Among them, Schmeissneria is seen in both the Middle Jurassic in China and Early Jurassic in Europe, and thus sheds much more light on the origin and early evolution of angiosperms.KeywordsMiddle JurassicShort ShootFemale InflorescenceYixian FormationInflorescence AxisThese keywords were added by machine and not by the authors.
