Living Large: The Secrets of Sauropods with picture of Sauropods in a line-up

What has a long neck, a tiny head, and is heavier than a family of elephants? A giant sauropod! These massive dinosaurs dominated Earth for 140 million years.

Hi, I'm Jonah Choiniere and I’m a paleontologist. To learn about extinct animals like sauropods, paleontologists hunt for fossils all over the world. But a lot of discoveries happen back in the lab.

Play the game in my lab below to find out how sauropods lived. You'll watch videos and gather clues from experts. And when you're done, you can download a sauropod poster!
