This is a list of the oldest-known trees, as reported in reliable sources. Definitions of what constitutes an individual tree vary. Definitions of what constitutes an individual tree vary. In addition, tree ages are derived from a variety of sources, including documented "tree-ring" ( dendrochronological ) count core samples, and from estimates.

Lepidodendron species were comparable in size to modern trees. The plants had tapering trunks as wide as 2 m (6.6 ft) at their base that rose to about 40 m (130 ft) [ 2 ] and even 50 m (160 ft), [ 1 ] arising from an underground system of horizontally spreading branches that were covered with many rootlets.
The Carboniferous lycophytes of the order Lepidodendrales, which were cousins (but not ancestors) of the tiny club-mosses of today, were huge trees with trunks 30 meters high and up to 1.5 meters in diameter. These included Lepidodendron (with its fruit cone called Lepidostrobus), Halonia, Lepidophloios and Sigillaria.
The second and sixth tallest trees, both redwoods, were also found at Redwood National Park in 2006 when Hyperion was found, and were named Helios 114.8 metres (377 ft), and Icarus 113.1 metres (371 ft) tall. [3]
Arthropleura is known from body fossils as well as trace fossils, particularly giant trackways up to 50 centimetres (20 in) wide, and potentially also large burrows. It lived in open, sparsely wooded environments near water, and was possibly amphibious.
The New York Times regarded the tree in a March 7, 1897 issue as the "most magnificent fir tree ever beheld by human eyes" and called its destruction a "truly pitiable tale" and a "crime". [ 5 ] [ 6 ] The Morning Times of February 28, 1897 claimed that the wood, sawed into one-inch strips, would reach from " Whatcom [the tree's location] to China".
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 ...
