“Ichˈthy-o-sauˈrus” (fish-lizard). This animal, which also is known only by its fossil remains, must have been about thirty feet long. It had enormous eyes, a long and large head, a mouth armed with powerful teeth, and a short neck. The body was fish-like in form, and the four paddles, resembling those of a whale, were comparatively small. The tail was long and gradually flattened toward the end; it was the principal organ of locomotion. They were very active in their movements, and consequently were dangerous enemies to all other animals living in the sea. Their food consisted chiefly of fishes.
