Ankylosaurus [nb 1] is a genus of armored dinosaur.Its fossils have been found in geological formations dating to the very end of the Cretaceous Period, about 68–66 million years ago, in western North America, making it among the last of the non-avian dinosaurs.
Ankylosaurinae is formally defined in the PhyloCode as "the largest clade containing Ankylosaurus magniventris, but not Shamosaurus scutatus". [2] [3] [4] The tribe Ankylosaurini is defined in the PhyloCode as "the largest clade containing Ankylosaurus magniventris, but not Pinacosaurus grangeri and Saichania chulsanensis".
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.
Skull diagram of Kunbarrasaurus. Parankylosaurs, compared to the more well studied euankylosaurs, retain more traits seen in more primitive thyreophorans and stegosaurs. This is most applicable in the body, most distinctively seen in the possession of rather long and slender limbs.
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.

Barun Goyot Formation in Mongolia. In 1970 and 1971 a Polish-Mongolian expedition found ankylosaurian fossils in the Gobi Desert near Chulsan, or Khulsan.. The type species Saichania chulsanensis was named and described by the Polish palaeontologist Teresa Maryańska in 1977, along with the related species Tarchia kielanae. [1]

Tarchia was a medium-sized ankylosaur, measuring around 5.5–6 metres (18–20 ft) long and weighing up to 2.5–3 metric tons (2.8–3.3 short tons). [9] [10] If ZPAL MgD I/113 indeed belongs to the genus, it would have belonged to an individual measuring 5.8–6.7 metres (19–22 ft) long.
