As you enter the Academy, feast your eyes on a display containing the daily diet of a young adult Mamenchisaurus—up to 1,150 pounds of plant matter per day!
The World's Largest Dinosaurs
Big news: The largest land animals that ever lived have arrived at the Academy! Get ready for a hot sauropod summer with life-size dinosaur models, hands-on interactives, and programs for junior paleontologists.
Take a deep breath: About one pint of air just filled your lungs. Got 173 more? That’s how much a 60-foot Mamenchisaurus hoovered up with every inhale. Talk about breathtaking!
At the Academy’s newest exhibition, you’ll get to gaze up at incredible, ancient, long-necked herbivores like Mamenchisaurus and Argentinosaurus; learn how they lumbered across every continent; and dig into research on present-day organisms helping paleobiologists understand how these dinosaurs thrived for 140 million years.
Now open daily. Watch the trailer!

Mamma Mamenchisaurus!
You won’t believe your eyes—or its size—when you marvel at a full-scale model of a female Mamenchisaurus spanning 60 feet long. Projections on the outside of the model give you an inside look at the dinosaur’s heart and lungs in action.

Telling the tooth
Paleobiologists think that the pencil-like teeth of Diplodocus allowed it to nip and strip the leaves from tree branches—a surprisingly delicate feat for a 13-ton sauropod.
