APA TEGESÉ SEED FERN ING BASA INGGRIS?

Pteridospermatophyta

Pteridospermatophyta

Istilah Pteridospermatophyta nuduhake sawetara klompok spesies tetanduran wiji sing wis pupus. Bukti fosil paling tuwa saka tetanduran iki yaiku genus Elkinsia saka umur Devonian pungkasan. Padha berkembang utamané ing jaman Carboniferous lan Permian. Pteridosperms nyatakake nalika jaman Mesozoic lan akeh banget ilang ing pungkasan periode Cretaceous, senadyan sawetara tetanduran kaya pteridosperm katon bisa urip ing jaman Eocene, fosil ing Tasmania. Konsep pteridosperma bali menyang pungkasan abad kaping 19 nalika para palaeotan ngenani manawa fosil-fosil Carboniferous sing mirip fern fronds nduweni fitur anatomi sing luwih mirip karo tanduran benih modern, cycads. Ing taun 1899, palaeobotanis Jerman, Henry Potonié mujudake istilah "Cycadofilices" kanggo fosil-fosil kaya mangkene, nyatakake yen ana klompok tetanduran non-benih ing antarane pakis lan cycads.

The term Pteridospermatophyta refers to several distinct groups of extinct seed-bearing plants. The oldest fossil evidence of plants of this type is the genus Elkinsia of late Devonian age. They flourished particularly during the Carboniferous and Permian periods. Pteridosperms declined during the Mesozoic Era and had mostly disappeared by the end of the Cretaceous Period, though some pteridosperm-like plants seem to have survived into Eocene times, fossilized in Tasmania. The concept of the pteridosperms goes back to the late 19th century when palaeobotanists came to realise that many Carboniferous fossils resembling fern fronds had anatomical features more reminiscent of the modern-day seed plants, the cycads. In 1899 the German palaeobotanist Henry Potonié coined the term "Cycadofilices" for such fossils, suggesting that they were a group of non-seed plants intermediate between the ferns and cycads.
