This slab shows the complete five-digit footprint of an early Permian Dromopus delicatulus, an amphibian. The footprints of of Dromopus delicatulus rarely show all five digits. A fossil slab that shows all five digits and or a pes-manus combination of Dromopus delicatulus, is truly rare--the stuff many natural-history museums would like to own. Slab is about 3/8 thick.
