This is Synde and George Langford's Christmas card in 1939. The picture is a view of the strip mines about 1 mile south of Wilmington, IL, at a place that was not far from where Cinder Ridge Golf Course is today. The fossil on the left was identified as Sphenophyllum emarginatum. It was originally named in 1829 by Adolphe-Theodore Brongniart, known as the Father of Paleobotany. It's a relative of modern day horsetails. While the one on the right, was identified as Diplothmema zobelli, now known as Sphenopteris spinosa. Sphenopteris was part of the forest understory. It was first described in 1841 by Heinrich Goppert.
