Vertebrate evolution boomed during the Devonian period some 400 million to 350 million years ago. Bony fishes diversified, sharks branched out, and the first amphibians—husky creatures the size of a small alligator—galumphed onto land. The Devonian Ocean Simulator lets you zoom through seas teeming with trilobites, mollusks, and a multitude of fishes, from jawless bottom-huggers to Dunkleosteus, a 6-meter predator with a bear-trap mouth. Click on the creatures swimming by to summon information about their identity, size, and habits. The animation is a prototype museum exhibit created by Christian Darkin, a London-based artist and writer.
