Parankylosauria

genus of reptiles (fossil)

Antarctopelta (; meaning 'Antarctic shield') is a genus of ankylosaurian dinosaur, a group of large, quadrupedal herbivores, that lived during the Maastrichtian stage of the Late Cretaceous period on what is now James Ross Island, Antarctica. Antarctopelta is the only known ankylosaur from Antarctica and a member of Parankylosauria. The only described specimen was found in 1986, the first dinosaur to be found on the continent, by Argentine geologists Eduardo Olivero and Robert Scasso. The fossils were later described in 2006 by paleontologists Leonardo Salgado and Zulma Gasparini, who named th

Stegouros (, meaning "roofed tail") is an extinct genus of ankylosaurian dinosaurs from the Late Cretaceous Dorotea Formation of southern Chile. The genus contains a single species, Stegouros elengassen, known from a semi-articulated, near-complete skeleton. Stegouros is a member of the Parankylosauria, a clade of small Gondwanan armored dinosaurs. It is characterized by its small body size and distinct arrangement of fused osteoderms forming a macuahuitl-like tail weapon.

Kunbarrasaurus (meaning "shield lizard") is an extinct genus of small ankylosaurian dinosaur from the Early Cretaceous of Australia. The genus contains a single species, K. ieversi.

Patagopelta (meaning "Patagonian shield") is an extinct genus of ankylosaurian dinosaur from the Late Cretaceous (upper Campanian–lower Maastrichtian) Allen Formation of Argentina. The genus contains a single species, P. cristata, known from several partial skeletons, isolated bones, and osteoderms. While originally described as a member of the family Nodosauridae, later discoveries provided support for parankylosaurian affinities. Patagopelta is a small armored dinosaur, comparable in size to the 'dwarf' nodosaurid Struthiosaurus, at about long. It is larger, more robust, and more heavily arm

Parankylosauria is a group of armored thyreophoran dinosaurs known from the Cretaceous of South America, Antarctica, and Australia. Most analyses place parankylosaurs as a member of the Ankylosauria, in which case the group would have split from other ankylosaurs during the mid-Jurassic period, despite this being unpreserved in the fossil record. Another analysis has proposed that parankylosaurs are instead a distinct lineage of non-ankylosaurian armored dinosaurs with more ancestral anatomy. Several parankylosaurs are characterized by a distinctive frond-like tail weapon (called a 'macuahuitl
