Patagopelta
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

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 armored than other paranklyosaurs such as Stegouros.
== Discovery and naming == The Patagopelta fossil material was found in sediments of the Allen Formation (Salitral Moreno locality) near General Roca, Río Negro Province, Argentina. This locality is dated to the upper Campanian to lower Maastrichtian ages of the Late Cretaceous period. The first remains were described in 1996 and often appeared in the literature as the "Argentinian ankylosaur". The fossil material consists of various osteoderms, a tooth, dorsal and caudal vertebrae, and femora. The Patagopelta holotype specimen, MPCA-SM-78, is represented by a cervical half-ring element.
