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.
