Like other ankylosaurids, Ankylosaurus had cervical half-rings (armor plates on the neck), but these are known only from fragments, making their exact arrangement uncertain. Carpenter suggested that when seen from above, the plates would have been paired, creating an inverted V-shape across the neck, with the midline gap probably being filled ...
Ankylosauridae (/ ˌ æ ŋ k ɪ l oʊ ˈ s ɔː r ɪ d iː /) is a family of armored dinosaurs within Ankylosauria, and is the sister group to Nodosauridae.The oldest known ankylosaurids date to around 122 million years ago and went extinct 66 million years ago during the Cretaceous–Paleogene extinction event.

Ankylosauria is a group of herbivorous dinosaurs of the clade Ornithischia.It includes the great majority of dinosaurs with armor in the form of bony osteoderms, similar to turtles.
Thyreophora was defined as a clade by Paul Sereno in 1998, as "all genasaurs more closely related to Ankylosaurus than to Triceratops". Thyreophoroidea was first named by Nopcsa in 1928 and defined by Sereno in 1986, as "Scelidosaurus, Ankylosaurus, their most recent common ancestor and all of its descendants". [6]
Strongylocentrotus purpuratus, a well-armoured sea urchin. Armour is evident in numerous animal species from both current and prehistoric times. Dinosaurs such as Ankylosaurus, as well as other Thyreophora (armoured dinosaurs such as Ankylosauria and Stegosauria), grew thick plate-like armour on their bodies as well as offensive armour appendages such as the thagomizer or a tail club.
Borealopelta (meaning "Northern shield") is a genus of nodosaurid ankylosaur from the Lower Cretaceous of what is today Alberta, Canada.It contains a single species, B. markmitchelli, named in 2017 by Caleb Brown and colleagues from a well-preserved specimen known as the Suncor nodosaur.
A robotic ankylosaurus tail shows that the tail club could break wood and bone with ease. This dinosaur's armour and club was used only on more threatening predators than Velociraptor. In the U.S version, it was known as Ankylosaurus, although Ankylosaurus itself lived in North America. The ankylosaurus in this fact have been Pinacosaurus.
Ankylosaurus and its characteristic tail club.. In zoology, a tail club is a bony mass at the end of the tail of some dinosaurs and of some mammals, most notably the ankylosaurids and the glyptodonts, as well as meiolaniid turtles.
