Ankylosaurs were herbivorous dinosaurs that lived during the Cretaceous (65-68 million years ago). As the evolution of Ankylosaurus progressed, they developed bony armor that covered their bodies in the form of plates, scutes and spikes, with some even developing armor on their eyelids. While their armor and bone-shattering tail club are thought to have been used for defensive purposes against predators such as Tyrannosaurus, it's possible that some of the armor on their head may have been used for display. Adult Ankylosaurs are believed to have reached up to 25 feet in length and weigh 3.3 tons!
