Known as “lizard feet” is a group of saurischian dinosaurs containing many large, quadripedal herbivores; such as, Diplodocus, the largest known terrestrial animal from the Jurassic and Cretaceous periods.

These “lizard feet” had five-toed feet, like lizards, but had little else in common with them. Among the largest beasts that ever walked the earth, these peaceful plant-eaters included giants the length of several buses, and heavier than perhaps a dozen big bull elephants. By Late Jurassic times, sauropods ranked among the most abundant of all plant-eating dinosaurs in lands as far apart as western North America, East Africa, and China.

Known as “lizard feet” is a group of saurischian dinosaurs containing many large, quadripedal herbivores; such as, Diplodocus, the largest known terrestrial animal from the Jurassic and Cretaceous periods.

The early Sauropodomorphs were Prosauropods (“before the lizard feet”). They included the first plant-eating dinosaurs, and most are believed to have lived before the much larger, herbivorous sauropods (“lizard feet”).
