What is the difference between Ankylosaurus and Saichania?

Ankylosaurus and Saichania are both armored dinosaurs from the Late Cretaceous period, but they belong to different genera and exhibit distinct characteristics. Ankylosaurus, primarily found in North America, is known for its large size and prominent club-like tail, while Saichania, discovered in Mongolia, is smaller and has a more robust body with a different arrangement of armor plates. Additionally, Saichania is considered to have been more heavily armored than Ankylosaurus, reflecting adaptations to its environment. Both dinosaurs, however, shared similar herbivorous diets and defensive strategies against predators.
