Glossopteridales is an extinct order of plants belonging to Pteridospermatophyta, or seed ferns, also known as Arberiales and Ottokariales. They arose at the beginning of the Permian (298.9 million years ago) on the southern continent of Gondwana, but became extinct at the end of the Permian period (251.902 million years ago), during the Permian-Triassic extinction event. The best known genus is Glossopteris, a leaf form genus. Other examples are Gangamopteris and . Midrib-less forms were common in the Early Permian whereas midrib forms were more common in the Late Permian.
