- Ankylosaurus was as large as a military tank and nearly as hard to attack, even though it was slow. Weighing about 10,000 pounds and measuring 30 feet long, scientists believe that the dinosaur couldn’t move any faster than a human can walk
- Its name comes from the Greek words for “fused lizard,” referring to its tough outer armor.
- Ankylosaurus also had a club-shaped tail. If a predator attacked, the low and heavy reptile would swing its tail with enough force that it could break the bones of its enemies.
- Fossils of Ankylosaurus have been found on every continent except Africa.
