America's presidents were colorful figures already, but with this prehistoric makeover, they're downright hilarious: Meet George Washingdonyx, the two-ton, 90-toothed Father of his Country; Thomas Jeffersaurus, author of the Declaration of In-dino-pendence; and Theodore Rexevelt, a roughand-ready conservationist who protected meat for carnivores. Along with profiles of Abraham Lincoln, Andrew Jackson, and Franklin Roosevelt, here are unforgettable images of a very different Mount Rushmore and a portrait gallery with depictions of Richard Nixonator and Jimmy Carteraptor.
