Title: Gerrothorax, Illustration
Caption: Gerrothorax is a giant amphibian that lived in the lakes and rivers of Europe more than 200 million years ago. This odd-looking predator measuring 3 ft. (1 m) long had gills. It may have used them for breathing on the river or lake bed, where it lay in wait for its prey.
