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]
