A beautiful example of the ammonite Dactylioceras that swam the shallow seas of the Jurassic period, over 180 million years ago.
It is thought that Dactylioceras was a slow-swimming scavenging ammonite based on flow-tank experiments - however, its poor swimming skills didn't prevent it from becoming one of prehistory's most successful ammonite species. Dactylioceras, as a species, managed to survive for over 100 million years (five hundred times longer than we've been on the planet) - only dying out in the mass extinction event that also killed off the dinosaurs sixty-five million years ago.
