Mesacanthus mitchelli is an early acanthodian fish from the Devonian Period, often referred to as a spiny shark due to its primitive characteristics linking cartilaginous and bony fish. These small, fast-swimming fish had defensive spines on their fins and are among the earliest jawed vertebrates, playing a crucial role in the evolutionary history of fish.
The Old Red Sandstone formation in Scotland is world-famous for preserving Devonian fish fossils in stunning detail. The rich fossil beds from this period document the transition of life from water to land and provide key insights into ancient marine ecosystems.
