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 ...
Restoration Leaf scars are shown between the vertical sections of a Sigillaria where the leaves used to be attached. Sigillaria was a tree-like plant reaching a height up to 30 m (98 ft), [1] and lycopsids were capable to reach a height of up to 50 m (160 ft). [4]
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 ...
The History Channel's original logo used from January 1, 1995, to February 15, 2008, with the slogan "Where the past comes alive." In the station's early years, the red background was not there, and later it sometimes appeared blue (in documentaries), light green (in biographies), purple (in sitcoms), yellow (in reality shows), or orange (in short form content) instead of red.
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 ]

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 ...
