From a quick glance, its easy to associate the Ankylosaurus with a bus or army tank. Its extremely tough exterior is such a unique sight. Their bones seemed to have formed with the skin, giving them features much like the crocodile. Most likely weighing in at around 4 tons, this amazing creature was said to have roamed the Western U.S. and Alberta, Canada. Along with the rough and tough exterior that looks like fused armor, the Ankylosaurus tail has a distinct tip used for protection. This creature is a simple herbivore and always ready to explore the world for delicious plant snacks.
