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.
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.

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 ...
These trees are both tall and large in diameter and, in particular, hold a large diameter high up the trunk. Measurement is very complex, particularly if branch volume is to be included as well as the trunk volume, so measurements have only been made for a small number of trees, and generally only for the trunk.
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.
Anecdotal reports do exist of other Douglas fir and mountain ash trees reaching 400 to 500 feet (122 to 152 m), such as the 435 ft (133 m) "Ferguson Tree," a Eucalyptus regnans of the Watt's river, Australia in 1872, or the 415 ft (126 m) Lynn Valley Tree, a Douglas fir felled in 1902. They are often dismissed as unreliable; however, some are ...
The Callixylon tree is an example of Callixylon whiteanum, a species of extinct trees found in the late Devonian period. [2] It was later discovered to be a member of the same family as the genus Archaeopteris. [3] It was a series of pieces that were eventually reconstructed to form a full eight foot tall stump. [4]
