"Struthiopteris" Natural Recordings by Native Speakers
Struthiopteris is a genus of extinct club mosses that lived during the Pennsylvanian and early Permian periods of the Paleozoic era. The name "Struthiopteris" comes from the Greek words "struthos," meaning ostrich, and "pteris," meaning fern, likely due to the shape of the leaves, which resembled the shape of an ostrich feather. They likely resembled modern-day club mosses but with leaves that were longer and more strap-like. The fronds were likely one to three feet in length, and the plant was epiphytic, growing on other plants for support.
