About
Gravisauria is a group of sauropod dinosaurs that contains Eusauropoda and the two-crittered-clade (Vulcanodon + Tazoudasaurus) known as Vulcanodontidae. Despite the name, not all members of Gravisauria (the "Heavy Lizards") were particularly heavy, as far as sauropods go. Some of them, however, were among the largest creatures ever to walk the earth.
