Aneurophyton

Aneurophyton is a genus of extinct vascular plants that belong to the Aneurophytales, a class of progymnosperms. The genus is primarily known from records of two well-known species found in mostly Middle Devonian and Upper Devonian (late Eifelian to Famennian) outcrops in Belgium, China (West Junggar), Germany, and the United States (New York).[1][2] Some uncertain species within the genus are also recorded from Middle Devonian outcrops in Kazakhstan, Russia (Timan and Siberia), and the Ukraine. While a number of species have been described in the paleobotanical literature, the genus likely only contains two well-circumscribed species, A. germanicum and A. doui,[1] and possibly a third species, A. olnense, from Fammenian outcrops in Belgium.[3] If the ages of the Early Devonian (Emsian) records of A. germanicum reported from Siberia are confirmed,[4] these would constitute the oldest records of this genus.
