This is a very pretty fossil plant. It is a split pair of Sphenophyllum flowers from Johnson County, Missouri. Sphenophyllum are the leaf whorls of an extinct horsetail. They are related to the modern-day scouring rushes. The four whorls have great detail preserved and are nicely showcased in the concretion. Both halves of the concretion are intact and offered together. This is a beautiful set of Sphenophyllum whorls preserved in a split pair concretion.
