The sauropods are a group of dinosaurs whose image is well known in popular Home-Earth culture. They are enormous four-footed browsers, long-necked and long-tailed, and were the dominant terrestrial herbivores throughout much of the Jurassic and Cretaceous. On Spec, the sauropods are alive and well, but nowhere near as widespread as during the Mesozoic. They are represented by a single lineage, the aptly named Titanosaurs the largest land-animals on the planet.
