Beauty comes from an unlikely source, courtesy of these gifted dino artists; here are Renaissance reptile Leonardo da Vilociraptor, brilliant but self-destructive saurian Vincent van Guanadon, and prehistoric selfportraitist Frida Kahlopholus. Art aficionados may spot a delightfully weird version of Grant Wood's American Gothic and wry send-ups of works by Botticelli, Rodin, Munch, Gauguin, and Magritte.
