Background The evolution of the Jehol Biota of western Liaoning in China includes three
phases, initiation in the Dabeigou phase, radiation in the Yixian phase, and decline in the …

Modern gnetophytes consist of three families, ie the Ephedraceae, the Gnetaceae, and the
Welwitschiaceae, which show diversified morphology. The basal group Ephedraceae …

evidence has so far been found to support an origin of the compact compound male cone …

In the present paper, an ephedroid macrofossil species from the Early Cretaceous Yixian
Formation of western Liaoning of China is described as new to science: Ephedra multinervia …

Although there are many reports of fossil Ephedraceae, whole plant fossil record remains
rare. Due to a lack of trust on partially preserved fossil materials, scholars working on …
