Remains of a Sigillaria tree, Stanhope, County Durham, UK
Fossil tree-root of lycopod

Sigillaria is a lycopod fossil of the late Carboniferous and early Permian.[1] They were typical coal forest trees similar to the Lepidodendron. These swamp forest trees grew to 50 meters. They were anchored by an extensive network of branching underground roots.[2]

It was a lycopod, an early land plant. This was one of the trees which made up the Carboniferous coal-forests.

It had thin grasslike leaves that grew on the stem. The stem of the plant was green. Sigillaria reproduced with spores. It went extinct about 300 million years ago.
