Petriellales is an extinct order of gymnosperms known from Middle Triassic (Olenekian) to Late Triassic (Rhaetian) floras of Gondwana, with fossil findings from Antarctica, Australia, southern Africa and South America. The family Petriellaceae is the only known family in the order. The order is characterized by fan-shaped leaves with anastomosing veins and forked reproductive structures represented by separate female ovulate and male microsporangiate organs. Petriellales plants are thought to have been part of humid understory vegetation of Triassic temperate forests, with fossil occurrences on the high latitudes of Southern Hemisphere.
