Both Bill and Kris Parsons, of the Buffalo Museum of Science, New York, found the dino skull on the hillside in Montana in 1997. They then continue the search and excavation to collect a nearly complete fossils, including skulls with protective layers, pieces of ribs, spine, and leg bones.
Animals, later named Tatankacephalus cooneyorum is a kind of Ankylosaurus, plant-eating dinosaur whose body was covered with a layer of bone. It may be colored layers, and similar material tortoise shell or beak.
"They are a large dinosaur that walked on four legs and a shielded like a Sherman tank," said Bill Parsons about the animal whose length reaches 4.5 to 6 meters.
In addition to plated steel, this dinosaur is equipped also with two pairs of pointy horns, one on his cheek and one pair again around her eyes. She has two thick layers at the back of the head and the hard part around the nose.
Bill Parsons believes, during his lifetime, T cooneyorum covered with hundreds or thousands of pieces of hard coating, hard on the dorsal fins, and spines on the tail, similar to Ankylosaurus.
To avoid predators, Ankylosaurus may bend his body on the ground and grabbed his head, while the horns on his head to protect from bites to the neck.
The species found are believed to be the kind that comes after a more primitive and Ankylosaurus is present then the horns are larger and more curved nose section.
