The zosterophylls are a group of extinct land plants that first appeared in the Silurian period. The taxon was first established by Banks in 1968 as the subdivision Zosterophyllophytina; they have since also been treated as the division Zosterophyllophyta or Zosterophyta and the class or plesion Zosterophyllopsida or Zosteropsida.
In the geological timescale, the Llandovery Epoch (from 443.8 ± 1.5 million years ago to 433.4 ± 0.8 million years ago) occurred at the beginning of the Silurian Period. . The Llandoverian Epoch follows the massive Ordovician-Silurian extinction events, which led to a large decrease in biodiversity and an opening up of ecosyste
Baragwanathia is a genus of extinct lycopsid plants of Late Silurian to Early Devonian age (), fossils of which have been found in Australia, Canada, China and Czechia.The name derives from William Baragwanath who discovered the first specimens of the type species, Baragwanathia longifolia, at Thomson River (Victoria, Australia).
Prototaxites / ˌ p r oʊ t oʊ ˈ t æ k s ɪ t iː z / is an extinct genus of terrestrial fungi dating from the Late Silurian until the Late Devonian periods. [1] [2] Prototaxites formed large trunk-like structures up to 1 metre (3 ft) wide, reaching 8 metres (26 ft) in length, [3] made up of interwoven tubes around 50 micrometres (0.0020 in) in diameter, making it by far the largest land ...
The flora of the Philippines boasts a diverse array of plant species given its location in the great Malaysian flora. The Malaysian Phytogeographic zone is considered to be one of the most important centers for plant diversity because of the multitude and variance of species occupying that zone. [ 1 ]
