Ventarura is a genus of extinct vascular plants of the Early Devonian (around 420 to 390 million years ago). Fossils were found in the Windyfield chert, Rhynie, Scotland. Some features, such as bivalved sporangia borne laterally and the anatomy of the xylem, relate this genus to the zosterophylls. Other features are unclear due to poor preservation.
