The ankylosaurus would win, although Velociraptors could easily kill young ankylosauruses, which have armor. The ankylosaurus is being attacked by three Velociraptors. They try to attack it four times but its armor proves thick. The ankylosaurus is able to drive them away by swinging its tail club (one hit would have killed one of the pack).
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.
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]
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. [1]
All ankylosaurians had armor over much of their bodies, mostly scutes and nodules, with large spines in some cases. The scutes, or plates, are rectangular to oval objects organized in transverse (side to side) rows, often with keels on the upper surface. Smaller nodules and plates filled in the open spaces between large plates.
Referred specimens include ZPAL MgD-I/114 consisting of an undescribed fragmentary skull roof and associated armour, and an undescribed, almost complete skeleton with skull, specimen PIN 3142/251. Later, also the juvenile specimen MPC-D 100/1305 was referred and extensively described in 2011, seeming for the first time to provide complete ...
Zuul is a genus of herbivorous ankylosaurine dinosaur from the Campanian Judith River Formation of Montana.The type species is Zuul crurivastator.It is known from a complete skull and tail, which represents the first ankylosaurin known from a complete skull and tail club, as well as the most complete ankylosaurid specimen thus far recovered from North America.
It preserves a series of eleven back vertebrae, ribs, a right hindlimb, and plates of the belly armour. [1] It was the first specimen of a thyreophoran discovered in the Southern Hemisphere . In 1989, a much more complete skeleton was discovered, specimen QM F1801 that includes the skull and shows an articulated body armour.
