Aachenosaurus
dubious genus of prehistoric plant named based on fragments of petrified wood
Sphenobaiera
Sphenobaiera is a form genus for plant leaves belonging to the order Ginkgoales found in rocks from Triassic to Cretaceous periods. The genus Sphenobaiera is used for plants with wedge-shaped leaves that can be distinguished from Ginkgo, Ginkgoites and Baiera by the lack of a petiole. It became extinct about . The family to which this genus belongs has not been conclusively established; an affinity with the Karkeniaceae has been suggested on morphological grounds.
Palmoxylon
Palmoxylon, also called petrified palmwood, is an extinct genus of palm named from petrified wood found around the world.
Sphenopteris
Sphenopteris is a genus of seed ferns containing the foliage of various extinct plants, ranging from the Devonian to Late Cretaceous. One species, S. höninghausi, was transferred to the genus Crossotheca in 1911.
