Nilssonia is an extinct genus of plants, called "cycadeoids," belonging to Bennettitales, which were similar to cycads in growth form and leaf morphology, but completely different in reproductive structures. Fossils of the cycadeoid Nilssonia are found in Triassic, Jurassic and Cretaceous-aged terrestrial strata of East Asia, Australia, North and South America.[2][3][4]
