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.
Late Devonian: 375 million years ago, 75% of species lost, including most trilobites; End Permian, The Great Dying: 251 million years ago, 96% of species lost, including tabulate corals, and most trees and synapsids; End Triassic: 200 million years ago, 80% of species lost, including all conodonts
Pando, a colony of quaking aspen, is one of the oldest-known clonal trees. Recent estimates of its age range up to 14,000 years old, and 18,000 years by the latest (2024) estimate. [1] It is located in Utah, United States. This is a list of the oldest-known trees, as reported in reliable sources. Definitions of what constitutes an individual ...
Unusual trees found fossilized in Canada were buried alive 350 million years ago. Scientists say the discovery opens a new window into the history of life on Earth. Rare ancient tree discovery has ...
Fossils of plants from the early Devonian show that a simple form of wood first appeared at least 400 million years ago, at a time when all land plants were small and herbaceous. [87] Because wood evolved long before shrubs and trees, it is likely that its original purpose was for water transport, and that it was only used for mechanical ...
All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA—and it likely lived on Earth only 400 million years after its formation.
Most of these plants have true roots and leaves, and many were quite tall. The tree-like Archaeopteris, ancestral to the gymnosperms, and the giant cladoxylopsid trees had true wood. These are the oldest known trees of the world's first forests. Prototaxites was the fruiting body of an enormous fungus that stood more than 8 meters tall. By the ...
One of the most diverse plant genera, known as Solanum — which includes crops such as potatoes, tomatoes and eggplants — first gained prickles 6 million years ago.
