The Legs are Brachiosaurus femora, upper hind leg bones from one of the largest animals to ever walk the earth. Brachiosaurus was a long- necked sauropod, a plant- eater that roamed the earth 150 million years ago in the Late Jurassic. It is commonly found in the Morrison Formation, just ten minutes away from the hotel. A full grown Brachiosaurus would have been over 80 feet long (24 m) and weighed about 30 tons. That’s about the length of two school buses and the weight of six female Asian Elephants!
