Pennsylavian Amphibian Trackways from Alabama

Description: These trackways were made by an unknown amphibian in the Early Pennsylvanian deposits of Alabama. They were most likely made over a short timespan while the mud was just the proper moistness to preserve them There is also a plant stem preserved in the lower third of the matrix block. I always enjoy seeing specimens such as this as they show a moment frozen in time when we can actually see what the trackmakers were doing.
