ANCHISAURUS
Anchisaurus was a Middle Triassic to Early Jurassic plant-eater about 7 to 10 feet long. It had five-fingered hands with a curved thumb claw, and its feet had five toes. Achisaurus had spoon-shaped teeth that were probably not used for chewing food, but rather for gathering it. Once it swallowed the food, its gizzard, a kind of grinding organ that used swallowed stones, did the "chewing." North America, Europe, and Africa were home to these low-walking dinosaurs. Perhaps the anchisaurs could raise themselves up on their hind legs for reaching plants above ground level.
