Final answer:
Although Ankylosaurus and turtles both have protective Armor, they are not anatomically similar since Ankylosaurus had osteoderms and turtles have shells made from their ribs and spine. The correct answer to whether Ankylosaurus is similar to common day turtles by their anatomical characteristics is false.
Step-by-step explanation:
Ankylosaurus is often compared to modern turtles because of its heavy, armoured body and slow movement, but it is important to clarify that they are not anatomically similar in detail. While both had protective shells, the Ankylosaurus was a dinosaur with features quite distinct from the turtles of the order Testudines. For instance, their armor was part of their skin in the form of bony plates called osteoderms, whereas turtle shells are an integral part of their skeletal system, forming from the ribs and spine. Therefore, it's not accurate to say that Ankylosaurus and common day turtles share similar anatomical characteristics, so the correct answer to the question is false.
