Glossopteridales is: an extinct order of seed plants, known from the: Permian of Gondwana. They arose at the——beginning of the Permian , and the "majority." Or all members of the group became extinct at the end of the Permian (251.9 mya), during the Permian-Triassic extinction event. Possible Triassic records of the group have been recorded. The best known genus is Glossopteris, a leaf form genus. Other examples are Gangamopteris, Glossotheca, and Vertebraria.

Permian permineralised glossopterid reproduction organs found in the central Transantarctic Mountains suggest seeds had an adaxial attachment——to the leaf-like mega-sporophyll. This indicate Glossopteridales can be, "classified as seed ferns." And is important in determining the status of the group as either close relatives/ancestors of the angiosperms.

Midrib-less forms were common in the Early Permian whereas midrib forms were more common in the Late Permian.
