Age: Upper Jurassic Rock unit: Morrison Formation

The Museum’s Late Jurassic sauropod, nicknamed Happy, is the only known adult specimen of this dinosaur complete enough to display in its entirety. This impressive dinosaur, the holotype of its species, was discovered by a Museum team in June 1954 at a dig site in Red Canyon, near Cañon City, Colorado. In life, this dinosaur was probably more than 72 feet long and 14 feet tall at the hips, with a weight of about 25 tons. This bone likely belongs to caudal chevron 11 or 12 based on the interesting asymmetry of muscle scars.
