Komlopteris was named by Barbacka in 1994, to include leaves originally included in
Thinnfeldia and
Pachypteris. The type species is
K. nordenskioeldii, known from the earliest Jurassic (Hettangian) of Sweden,
K. speciosa from the Middle Jurassic (
Bathonian)
Taynton Limestone Formation of England, and
K.
distinctiva from the Early Jurassic of Poland. The oldest species from
Gondwana are from Argentina, dating to the Early Jurassic, assigned to the species,
K.
artabeae and
K. nestarensis ,which were originally assigned to the genus
Alicurana, which was considered a synonym of
Komlopteris in a 2023 review of the genus. Species known from the Late Jurassic include
K. khatangiensis from India,
K. constricta from the Antarctic Peninsula, and
K.
purlawaughensis from the
Talbragar Fish Bed in NSW, Australia.
K.
tiruchirapalliense is known from the Early Cretaceous of both southern India and Western Australia. Other Early Cretaceous species include
K.
indica from the Indian subcontinent,
K.
boolensis from Australia (Victoria and Queensland), and
K.
victoriensis from the Early Cretaceous of Victoria, Australia and New Zealand, and the early Late Cretaceous (
Cenomanian) of Queensland, Australia. The youngest known species is
K. cenozoicus from the early Eocene (
Ypresian) of Tasmania, which are the youngest known remains of any "seed fern". == References ==
