Climatius reticulatus is one of the earliest known acanthodians, often called spiny sharks due to their sharp defensive fin spines. These ancient fish lived in shallow Devonian seas, evolving as one of the first jawed vertebrates, making them a crucial species in the evolutionary transition from early fish to modern sharks and bony fish.
The Old Red Sandstone of Scotland is world-renowned for its exceptional preservation of Devonian fish, providing a unique window into early marine ecosystems over 400 million years ago. The Tillywhandland Quarry is an especially important fossil site, yielding some of the best-preserved fossil fish from this time period.
This Climatius reticulatus fossil is part of the Alice Purnell Collection, one of the largest and most respected fossil collections in the world. We specialise in museum-quality fossils, making this a perfect piece for collectors, researchers, and museums.
