Fossil Catalina Ironwood From Aldrich Hill, Nevada

This is a leaf fragment from Lyonothamnus parvifolius, the fossil equivalent of the modern Catalina ironwood (Lyonothamnus floribundus) and channel ironwood (Lyonothamnus asplenifolius)--also called Lyon Tree, both now restricted in native habitat solely to the Channel Islands off the coast of Southern California. The specimen is roughly 25mm in actual length and was collected from the middle Miocene Aldrich Station Formation, Nevada.
