Psilophyton is a genus of extinct vascular plants. Described in 1859, it was one of the first fossil plants to be found which was of Devonian age (about 420 to 360 million years ago ). Specimens have been found in northern Maine , USA; Gaspé Bay , Quebec and New Brunswick , Canada; the Czech Republic ; and Yunnan , China.
The class was created in 1917 by Kidston and Lang for fossils found in the Rhynie Chert Bed. [4] Three genera were initially included, Rhynia, Horneophyton and Psilophyton. All lacked leaves and true roots, consisting only of branched stems; however they were considered to contain vascular tissue. [1] Additional fossil genera were added later.
Trimerophytopsida (or Trimeropsida) is a class of early vascular plants from the Devonian, informally called trimerophytes.It contains genera such as Psilophyton.This group is probably paraphyletic, and is believed to be the ancestral group from which both the ferns and seed plants evolved.
The Trout Valley Formation also contains fossilized Psilophyton plants, as well as a number of other taxa, including Pertica quadrifaria, the official state fossil, [3] the tallest plant of its age known from anywhere in the world.

Fossils which have been placed in this genus have been found, among other locations, in Wales in formations of Early Silurian age (Přídolí, around 4] in the Wutubulake Formation in Xinjiang, China, of the same age; [5] in the Paraná basin, Brazil, from the Early Devonian (Lochkovian, around 6] and in Belgium from an outcrop of Early ...
