Coniopteris is an extinct genus of
cladistic analysis found it to be a stem group of Polypodiales.[1] Most species of Coniopteris probably had a herbaceous habit.[1] Coniopteris laciniata had tufts of leaves sprouting from intervals of a thin, creeping rhizome.[2] The genus is technically a junior synonym of the little used Polystichites, but was conserved by the ICZN in 2013.[3] Some authors suggest a range of Early Jurassic-early Late Cretaceous for the genus,[1] while others suggest a more expansive range spanning from the Middle Triassic to the Eocene.[4]
