Dicroidium is an extinct genus of fork-leaved seed ferns that were distributed over Gondwana 252 to 201 million years ago during the Triassic period. Their fossils are known from South Africa, Australia, New Zealand, South America and Antarctica. They were first discovered in Triassic sediments of Tasmania by Morris in 1845. Fossils from the Umm Irna Formation in Jordan indicate that these plants already existed in the Late Permian period.
