Oldengate Bridge is a fossil gateway composed of the giant bones of a Brachiosaurus, one of the largest creatures that ever walked the earth. It stands fifty-two feet tall and more than eighty feet long. A peaceful plant-eater, the Brachiosaurus' enormous neck allowed it to browse amid the upper branches of prehistoric forests. This replica fossil is cast from bones discovered in Colorado in 1900, and the original is now in the Field Museum in Chicago.
