Lepidodendron ("scale tree") was a tree-like plant related to modern lycopsids that existed in the Carboniferous period.

DescriptionEdit

Lepidodendron bark

Lepidodendron bark. Note the scale-like pattern present on the surface.

Lepidodendron was a large plant, reaching heights in excess of 30 meters. The trunks often measured a meter or more in diameter, and rarely branched.[1] Lepidodendron bark resembled scales, giving the plant its name, and it was often mistaken for petrified reptile skin in the 19th century.[2] All of the foliage was concentrated at the top of the plant, and the leaves were long and thin.

ClassificationEdit

Instead of being a true club moss as often cited, Lepidodendron was actually more closely related to today's quillworts. About 150 species exist today.[3]

PaleobiologyEdit

Lepidodendron did not produce true seeds; rather, they reproduced by means of spores. Plants grew quickly, and on average they lived for 10 to 15 years.[4]
