Lepidodendron is an extinct genus of primitive lycopodian vascular plants belonging the order Lepidodendrales. It is well preserved and common in the fossil record. It is well preserved and common in the fossil record.
Specifically, the generic name Lepidodendron is typically used to describe compression specimens which feature a particular type of leaf cushion morphology. [ 6 ] In addition, many "organ taxa" have been identified to the Lepidodendrales: roots ( Stigmaria ), leaves, and cones ( Lepidostrobus ) were originally given a different genus and ...
They are one of the oldest lineages of extant (living) vascular plants; the group contains extinct plants that have been dated from the Silurian (ca. 425 million years ago). [ 2 ] [ 3 ] Lycophytes were some of the dominating plant species of the Carboniferous period, and included the tree-like Lepidodendrales , some of which grew over 40 metres ...
It was discovered in 1887 and contains the fossilised stumps and the stigmarian system of eleven extinct Lepidodendron lycopsids, [1] which are sometimes described as "giant club mosses" but are more closely related to quillworts. The Fossil Grove is managed as a museum and has been a popular tourist attraction since it opened for public ...
This genus is known in the fossil records from as early as the Middle Devonian or the Late Carboniferous period [1] but dwindled to extinction in the Early Permian period (age range: from 383.7 to 254.0 million years ago). [2] Fossils are found in Great Britain, United States, Canada, China, Korea, Tanzania and Zimbabwe. [3]
However, the composition of the forests changed from a lepidodendron-dominated forest to one of predominantly tree ferns and seed ferns. The Carboniferous rainforest collapse ( CRC ) was a minor extinction event that occurred around 305 million years ago in the Carboniferous period. [ 1 ]
The cladoxylopsids are an extinct group of plants related to ferns and sphenopsids. [1] They had a central trunk, from the top of which several lateral branches were attached. Fossils of these plants originate in the Middle Devonian to Early Carboniferous periods (around ), mostly just as stems.
While extinct in the wild, Encephalartos woodii specimens are found in many botanical gardens, institutions and collections around the world, with an estimated 500 individuals in existence, all clones of the original specimen. [2] [11] For an Encephalartos cycad, E. woodii is relatively fast-growing and vigorous in cultivation. [11]
