This tree is extinct, if you see it, then you have fallen into some sort of rip in the fabric of time The Lepidodendron (scale tree) was a large, treelike, climbing plant with broad, strap-like leaves. It existed mainly during the Carboniferous and Permian periods (roughly 300-248 million years ago). This tree, like most trees from the Carboniferous Period, were not like modern trees in that they reproduced by spores like a fern.
