It says that the height of Ankylosaurus is 2-3 meters (6-10 feet), while the poster says it's 11 feet. I find both to be absurdly tall, since the largest one every found in real life, the tallest Ankylosaurus was 1.7 metres tall (or 5.6 feet). Roughly half of the poster's given height.
Should we include the real-life height, like what we did with Spinosaurus?
