Ankylosaurus

Ankylosaurus was a genus of armored, plant-eating dinosaur that lived in North America during the Late Cretaceous. Its bony armor and heavy tail club made it distinctive.

Ankylosauria: Ankylosauria is a group of herbivorous dinosaurs with extensive body armor, including ankylosaurids and nodosaurids. Ankylosaurus belongs to this broader group of armored dinosaurs.
Dinosaur armor: Dinosaur armor consists of bony structures, such as plates, spikes, or scutes, in or beneath the skin. Ankylosaurus's armor formed a protective covering across much of its body.
Ankylosaurus magniventris: Ankylosaurus magniventris is the type species and only named species of the genus Ankylosaurus. This species is the basis for the genus's familiar reconstruction.
Barnum Brown: Barnum Brown was an American fossil collector and paleontologist who worked for the American Museum of Natural History. Brown discovered the first Ankylosaurus fossils in Montana in 1906.
Ankylosauridae: Ankylosauridae is a family of armored dinosaurs whose members typically had tail clubs. Ankylosaurus is a member of this tail-club-bearing family.
Quadrupedalism: Quadrupedalism is locomotion using all four limbs for support and movement. Its broad, low-slung body was supported by four sturdy limbs.
Ankylosaurus fossil specimens: Ankylosaurus fossil specimens are fragmentary remains from Late Cretaceous deposits in western North America. The known material is limited, leaving parts of the animal's anatomy uncertain.
Hell Creek Formation: The Hell Creek Formation is a Late Cretaceous and earliest Paleocene rock formation in the western United States. Ankylosaurus fossils are known from this formation's Late Cretaceous deposits.
Osteoderm: An osteoderm is a bony structure that forms within the skin of some vertebrates. Its armor included osteoderms embedded in the skin.
Dinosaur dentition: Dinosaur dentition is the structure and arrangement of teeth, which varied with diet and feeding strategy. Its small, leaf-shaped teeth suited a herbivorous diet.
