Ever since I was a kid, ankylosaurus has been my favorite dinosaur, but I (still) don't know much about them. What kind of things do palaeo artists mess up for them, and what should they look like?
Frankly, there aren’t a lot of super common mistakes with Ankylosaurus, besides getting the armour completely wrong.
One thing I am sceptical about is the body; other derived ankylosaurids are pancake-shaped whereas Ankylosaurus seems to be more of a corn dog. I wouldn’t be surprised if it got a makeover with new material, much like Stegosaurus has gotten.
