Alethopteris is a prehistoric plant genus of fossil Pteridospermatophyta (seed ferns) that developed in the Carboniferous period (around 360 to 300 million years ago). [1]
It is in the family Alethopteridaceae. The genus Alethopteris is among the seed ferns ( Pteridospermales), an extinct group of gymnosperms. Although their foliage resembled that of modern ferns, they reproduced by means of seeds.
