Fossil Trackway

Fossilized trackway of the ancient salamander Cincosaurus cobbi collected from the Crescent Valley Mine in Walker County. The fossilized footprint pattern, approximately 12 inches (30 centimeters) long, is one of numerous trackways of many types of animals that once lived in a delta and riverine environment during the Carboniferous period, approximately 300 to 360 million years ago.
