Provenance: A Tennessee fossil collection. Found on a privately owned farm in Campbell County, Tennessee. Lepidondendrons were among the first large trees to appear on earth. These long extinct tall spore-bearing trees were related to modern club mosses. They stood in a dense, swampy forest 320 million years ago contemporaneous with the first appearance of land animals. These Giant Club Moss trees somewhat resembled modern palms crowned with spiky fronds. The green trunks were textured like alligator skin, giving them the name "scale bark" trees. Price on request.
