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 ...
[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.
As Boise residents seek shelter from extreme heat this summer, tree canopies may seem like the perfect relief outdoors.But those leafy branches pose another unexpected danger that comes with the ...
The sand inside the trunks became solid rock, and the outer bark of the lycopsids became a thin layer of coal. Though some trunks are elliptical, especially the tallest, Lepidodendron lycopsids were typically circular. The deformations were likely caused by the force of the rising flood waters that filled the trunks with sand, as indicated by ...
