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.
Lepidodendrales (from the Greek for "scale tree") or arborescent lycophytes are an extinct order of primitive, vascular, heterosporous, arborescent (tree-like) plants belonging to Lycopodiopsida. Members of Lepidodendrales are the best understood of the fossil lycopsids due to the vast diversity of Lepidodendrales specimens and the diversity in ...
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 ...
Some extinct groups, such as zosterophylls, fall outside the limits of the taxon as defined by the classifications in Table 1 above. However, other extinct groups fall within some circumscriptions of this taxon. Taylor et al. (2009) and Mauseth (2014) include a number of extinct orders in their division (phylum) Lycophyta, although they differ ...

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]
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 ...
