Patagopelta (meaning "Patagonian shield") is an extinct genus of nodosaurine dinosaur from the Late Cretaceous (upper Campanian–lower Maastrichtian) Allen Formation of Argentina. The genus contains a single species, P. cristata, known from a partial skeleton. Patagopelta is a very small ankylosaur, comparable in size to the dwarf nodosaurid Struthiosaurus.[1]
Discovery and naming
The first remains of Patagopelta were described in 1996 and often appeared in the literature under the name "Argentinian ankylosaur".[2][3] New remains described in 2022 allowed it to be named as a new taxon under the name Patagopelta cristata. The generic name, "Patagopelta", means "Patagonian shield", while the specific name, "cristata", means "crested" in Latin, referring to the large crests on its cervical osteoderms and femur.[1]
Classification
In their phylogenetic analyses, Riguetti et al. (2022) recovered Patagopelta as a member of the Nodosaurinae, within a clade of entirely North American nodosaurids from the middle of the Cretaceous period. The cladogram below displays the results of their phylogenetic analyses.[1]
