Guests are greeted by the enormous head of an Argentinosaurus, considered to be the world’s largest sauropod at up to 140 feet long and 90 tons. Inside, a 60-foot-long Mamenchisaurus spans the length of the exhibition hall. Stand up straight: How do you measure up next to a 15-foot-tall Supersaurus hind leg?

Take a deep breath: About one pint of air just filled your lungs. Got 173 more? That’s how much a Mamenchisaurus hoovered up with every inhale. Be blown away by this Jurassic giant and other ancient herbivores in the Academy's newest exhibition, open daily.

The need for feed
To get big, you have to eat big—and for a young adult Mamenchisaurus, that meant munching up to 1,150 pounds of plant matter per day. See what a hungry sauropod could scarf up in an hour at this interactive feeding station.
Ancient history is at your fingertips throughout the exhibition. Touch and compare sauropod teeth with those of today’s animals, activate a zoetrope to watch a sauropod herd in motion, and lift a surprisingly light sauropod neck bone.
Feel the beat
Look up: A life-size model reveals how Mamenchisaurus’s circulatory and respiratory systems kept its blood flowing and lungs going. Like birds, its lungs received oxygen on both inhale and exhale, meaning it spent half as much energy on breathing as a sauropod-sized elephant would.
The World's Largest Dinosaurs is open daily through January 21, 2024. Find it in the Forum Gallery on Level Two, directly above the Academy Café.
