This fossil is of a lobed-finned fish named Osteolepsis macrolepidotus and was found in Scotland. The Devonian Period (named after fossils first found in Devon, England), is known as "The age of fishes" and was fish transformed into three major groups: lobe-finned, ray-finned, and sharks.

Even better when there are conodonts!
