Biology:Coniopteris
Coniopteris is an extinct genus of Mesozoic fern leaves. It was widespread over both hemispheres during the Jurassic and Early Cretaceous, with over 130 species having been described.[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] Coniopteris is traditionally assumed to have been a member of Dicksoniaceae (which are mostly tree ferns) or a close relative of Thyrsopteris. However, these affinites have been doubted by a number of authors. A 2020 cladistic analysis found it to be a stem group of Polypodiales, as many Coniopteris species share with these ferns vertically orientated and an incomplete annulus.[1] However, this feature is not preserved among many Coniopteris species, and several species from the Northern Hemisphere a complete and obliquely orientated annulus, suggesting a Cyatheales (to which Dicksoniaceae belongs) affinity for at least these species, though they are alternatively suggested to be close to the base of Cyatheales.[3] The genus is technically a junior synonym of the little used Polystichites, but was conserved by the ICZN in 2013.[4] 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.[5]
