Lepidodendron is an extinct genus of primitive lycopodian vascular plants belonging the order Lepidodendrales.It is well preserved and common in the fossil record. Like other Lepidodendrales, species of Lepidodendron grew as large-tree-like plants in wetland coal forest environments.
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 ...
During the Carboniferous, tree-like plants (such as Lepidodendron, Sigillaria, and other extinct genera of the order Lepidodendrales) formed huge forests that dominated the landscape. Unlike modern trees, leaves grew out of the entire surface of the trunk and branches, but fell off as the plant grew, leaving only a small cluster of leaves at ...
Associated fossil wood suggests that this specimen died inside a Lepidodendron tree trunk. [1] In 1987, Jennifer A. Clack suggested that a different embolomere, Eogyrinus attheyi from Newsham, Northumberland, belonged to the same genus as Pholiderpeton. She subsumed the genus Eogyrinus into Pholiderpeton and created the new combination P ...
[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 (130 ft) in height, although extant lycophytes are relatively small plants. [4] The scientific names and the informal English names used for this group of plants are ambiguous.
You will hear from some of the researchers and therapists working to help them cope, and you will come to understand some of the demons that veterans bring home from battle. However we individually feel about the U.S. wars in Iraq and Afghanistan, these enduring moral wounds, to young Americans who fought on our behalf, must be counted among ...
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 underground organs or structures of these lycopsids is referred to as Stigmaria. [4]
