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 (Mya) during the Silurian and Devonian periods, [2] [3] [4] with the ...
The Silurian was the first period to see megafossils of extensive terrestrial biota in the form of moss-like miniature forests along lakes and streams and networks of large, mycorrhizal nematophytes, heralding the beginning of the Silurian-Devonian Terrestrial Revolution.
During the Late Silurian and Devonian, land plants, assisted by fungi, [45] [46] underwent a hugely significant phase of evolution known as the Silurian-Devonian Terrestrial Revolution. [47] [48] Their maximum height went from 30 cm at the start of the Devonian, to 30 m archaeopterids, [49] at the end of the period.
The Devonian (/ d ə ˈ v oʊ n i. ən, d ɛ-/ də-VOH-nee-ən, deh-) [9] [10] is a geologic period and system of the Paleozoic era during the Phanerozoic eon, spanning 60.3 million years from the end of the preceding Silurian period at 419.62 million years ago (), to the beginning of the succeeding Carboniferous period at 358.86 Ma.
By the middle of the Devonian, several groups of vascular plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants (pteridospermatophytes) appeared. This rapid evolution and colonization process, which had begun during the Silurian, is known as the Silurian-Devonian Terrestrial Revolution.
It is classified as a terrestrial, freshwater, or marine animal, depending on the situation. Forests, inland wetlands, marine neritic, marine intertidal, and marine coastal/supratidal areas are ...
The deglaciation at the end of the Homerian glacial interval was coeval with the first major radiation of trilete spore-producing plants, harbingering the dawn of the Silurian-Devonian Terrestrial Revolution.
The best films are usually collaborations — and E.T. was no exception.. On Saturday, Jan. 25, legendary director Steven Spielberg and star Drew Barrymore opened up about their work on E.T. the ...
