The Age of Reptiles is a 110-foot (34 m) mural depicting the period of ancient history when reptiles were the dominant creatures on the earth, painted by Rudolph Zallinger. The fresco sits in the Yale Peabody Museum in New Haven, Connecticut, and was completed in 1947 after five years of work. The Age of Reptiles was at one time the largest painting in the world, and depicts a span of nearly 350 million years in Earth's history.
