The chain fern (Woodwardia sp.) is a modern fern that today grows mainly in western North America. Each frond typically grows 1 - 3 metres long, and although habitat preference varies between species, ferns of this genus are often found in the undergrowth of moist coniferous forests. Fossils of Woodwardia have been found in Washington state, USA, dating back to at least the Middle Miocene. Its fossils have also been discovered at the Hell Creek Formation, dating back to the end of the Late Cretaceous.
