7.3" Fossil Fern (Sphenopteris & Lyginopteris) Plate - Alabama

This is a beautiful, two fern fossil (Sphenopteris and Lyginopteris) from the Pottsville Formation, Alabama. This amzing specimen contains fronds of two seed ferns. They are so well preserved, venation is still visible in the leaves. Sphenopteris has four branches and shorter leaflets while Lygenopteris four branches and looks more like modern ferns.

Both are genera of seed fern that contain extinct species of fern that reproduced from seed as opposed to sporophyte reproduction of most modern ferns.

Comes with an acrylic stand.
