A large herbivorous dinosaur from the Late Cretaceous period, famous for its heavily armored body covered with bony plates and a club-like tail.
From Greek 'ankylos' (stiff, fused) + 'sauros' (lizard). Named in 1908 by paleontologist Henry Fairfield Osborn, who recognized that its distinctive fused skeletal structure made it unique among dinosaurs.
Ankylosaurus, the world's most famous armored dinosaur, was basically a prehistoric Sherman tank—it could be 35 feet long but weighed less than you'd think because its bones were fused for strength, not weight! Its tail club could smash other dinosaurs with tremendous force.
