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. It was named by Barnum Brown in 1908; it is monotypic, containing only A ...
Size compared to a 1.8 m tall human. Talarurus was a medium sized ankylosaur, Thomas Holtz and Gregory S. Paul estimated its length at 5–6 m (16–20 ft), Paul gave a weight of 2 t (2,000 kg), [9] however, Holtz estimated it around 454 to 907 kg (1,001 to 2,000 lb). [10]
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.

Gargoyleosaurus was a relatively small ankylosaur, reaching 3–3.5 m (9.8–11.5 ft) in length and 300–754 kg (661–1,662 lb) in body mass. [3] [4] [5] Much of the skull and skeleton has been recovered, and the taxon displays cranial sculpturing, including pronounced deltoid quadratojugal and squamosal bosses.
Among the ankylosaurids, Euoplocephalus was exceeded in size only by Ankylosaurus, and perhaps Tarchia and Cedarpelta. Euoplocephalus was about 5.3 metres (17 ft) long and weighed about 2 metric tons (2.2 short tons). [1] Like other ankylosaurids, it had a very broad and flat low-slung torso, about four feet high, positioned on four short legs.
Ford & Kirkland (2001) originally gave Aletopelta an estimated length of 6 metres (19.7 feet). [2] However, Gregory S. Paul gave a lower estimate of 5 metres (16 feet) long and weight of 2 tonnes (4,409 lbs) in 2010.
