Minmi
It had bony protrusions on its head, back, abdomen, legs and along the tail. Several types of armour are known in place in Minmi, including small ossicles, small keeled scutes on the body, large scutes without keels on the snout, large keeled scutes on the neck, shoulders, and possibly tail, spike-like scutes on the hips, and a combination of ridged and keeled scutes and triangular plates on the tail. There was one preserved ring of scutes around the neck. The arrangement of armour is unclear on the tail, although the triangular plates may have run on the sides of the tail, with long scutes forming a row along the top of the tail.  However, unlike other ankylosaurians, Minmi had horizontal plates of bones that ran along the sides of its vertebrae (hence its species name, M. paravertebra).
