Annularia is the form taxon given to the fossilized leaves of the extinct tree-like horsetail Calamites. These plants are closely related to and resemble modern horsetails though they often grew much larger than any modern horsetail, up to 30 feet (9.41m) and had branching growth that gives it a tree-like quality.

This specimen is approximately 9.5cm x 7.5cm and was scanned using Agisoft Photoscan.
