Not only is Ankylosaurus the widest of all dinosaurs, but it's the most heavily armored, with bony plates, studs, and spikes lining its entire back-even its eyelids have spikes. In addition, its tail has a thick knob of bone at the end of it, believed to have been used as a very formidable club against its enemies.
