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).
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
Cooksonia is an extinct group of primitive land plants, treated as a genus, although probably not monophyletic.The earliest Cooksonia date from the middle of the Silurian (the Wenlock epoch); [1] the group continued to be an important component of the flora until the end of the Early Devonian, a total time span of .
Artist interpretation of a Devonian swamp forest scene. Artwork by Eduard Riou from The World Before the Deluge 1872. The Silurian-Devonian Terrestrial Revolution, also known as the Devonian Plant Explosion (DePE) [1] and the Devonian explosion, was a period of rapid colonization, diversification and radiation of land plants and fungi on dry lands that occurred 428 to 359 million years ago ...
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 ...
