Annularia sp.
Age: Pennsylvanian
Formation: Braidwood

Here is a pretty specimen of Annularia sp. from the Coal Age of Missouri. Annularia represents a whorl of leaves found at the node of a Calamites plant. The fossil has great color and contrast. The leaves are very nicely exhibited. The fossil is preserved in a siderite concretion. Both halves of the concretion are present. This is a nice example of this Pennsylvanian plant from the mid-continent.
