Kelumapusaura (meaning "red earth lizard") is a genus of saurolophine hadrosaur from the Late Cretaceous Allen Formation in what is now Patagonia in Argentina. The type and only species is K. machi, known from a bonebed of various individuals.[1]

Etymology

The generic name, "Kelumapusaura," combines "kelumapu," the Mapudungun word for "red earth," and the feminine form of the Greek "sauros," meaning "lizard." The specific name, "machi," is derived from a word from the Mapuche people for "shaman."[1]

Description

The describing authors estimate that Kelumapusaura would have been 8 to 9 metres (26 to 30 ft) long.[1]

Phylogeny

Depicted below is a reproduction of the phylogenetic tree produced by Rozadilla et al. (2022), including Kelumapusaura and Huallasaurus, which was described in the same study.[1]

Paleoecology

Huallasaurus is known from the Late Cretaceous Allen Formation of Río Negro Province, Argentina. Many other dinosaurs, including titanosaurs, hadrosaurids, abelisaurids, dromaeosaurids, and alvarezsaurids have been named from the formation.[1]
