An Osteolepis macrolepidotus fossil is preserved in a dark stone slab, with a broad head and rows of overlapping, diamond-shaped scales extending along the curved body. Its specimen label identifies the Eifelian Devonian Sandwick Fish Bed at Tronston, Orkney, Scotland. Osteolepis was a lobe-finned fish from the ancient lake environments of the Orcadian Basin. Its paired fins had an internal bony framework, and it belongs to the broader evolutionary group from which four-limbed vertebrates arose. The heavy scales characteristic of these fishes had a hard outer covering known as cosmine. A crack on the reverse has been filled. The stone measures approximately 8.5" wide x 1" thick x 6.25" tall.
