Brontosaurus was a giant dinosaur with a super long neck and a super long tail. It was one of the biggest animals that ever walked on land! Brontosaurus was so heavy that the ground probably shook when it walked.
This big dinosaur was a plant eater. It used its long neck to reach leaves high up in tall trees, kind of like a giraffe. Brontosaurus lived in groups to stay safe from meat eaters. Even though it was huge, it was a gentle giant.
