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 ...
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 Paleozoic swamps had tree-like lycopsids that grew up to 30 m (98 ft), [2] and even 50 m (160 ft) in height. [3] These lycopsid plants were anchored by an extensive network of branching underground structures with root-like appendages attached to them.
The good news for the milkvetch plant is that they usually need wildfire to sprout — meaning dormant seeds now have a massive new habitat for a new crop of the rare shrub.
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 ]
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 on the placement of some genera. [12] [10] The orders included by Taylor et al. are: [12]
