Sphenopteris is a genus of seed ferns containing the foliage of various extinct plants, ranging from the Devonian to Late Cretaceous.^[1]^[2]

Biology

The frond of Sphenopteris could be up to 20 inches (51 cm) long.^[1]

In Brazil, fossil of form genus Sphenopteris was located in outcrop Morro Papalé in the city of Mariana Pimentel. They are in the geopark Paleorrota in Rio Bonito Formation and date from Sakmarian in Permian.^[3] Fossils of Sphenopteris have also been found in the Valle Alto Formation, Caldas, Colombia, among many other locations.^[4]
