Lepidodendron species were comparable in size to modern trees. The plants had tapering trunks as wide as 2 m (6.6 ft) at their base that rose to about 40 m (130 ft) [ 2 ] and even 50 m (160 ft), [ 1 ] arising from an underground system of horizontally spreading branches that were covered with many rootlets.
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 ...
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] These lycopsids had a tall, single or occasionally forked trunk [2] that lacked wood. Support came from a layer of closely packed leaf bases just below the surface of the trunk, while the center was ...
The Carboniferous coal swamps of West Virginia were dominated by ground pines of the genus Lepidodendron that could reach more than 100 feet in height. Sigilaria, however, was the largest tree and could be up to six feet in diameter at the base. [10] Other Carboniferous plant fossils in West Virginia include the leaves of seed ferns Alethopteris.

A test that identifies biomarkers associated with autism just became available in most states. It's meant to help rule out autism in children who have higher likelihoods of it.
[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.
It often only takes but a sip of an almond granita from Zero Gradi or even the sight of rare Ballini Farms strawberry-tree honey in a market to understand the lure of this Tuscan Archipelago location.
