Macrofossil evidence unveiling evolution and ecology of early Ephedraceae

The Early Cretaceous Yixian Formation from western Liaoning in northeastern China is well known for its extremely high diversity of plant macrofossils including important basal members of the Gnetales. The Gnetales from the Yixian Formation currently play a significant role in our present understanding of evolution and adaptation within the group. In the present paper the ephedroid macrofossil genus Prognetella Krassilov et Bugdaeva previously...
