Etymology
editDhanguura comes from the Aboriginal word "dhanguurr", meaning "fish", in the Wiradjuri tribe's language, because they inhabited the area, west of Wee Jasper. The species name, "johnstoni" is in honor of the discoverer of the genus, Dr. Paul Johnston, who found Dhanguura in 1993.[1]
Description
editDhanguura is known from fossilized remains of an incomplete skull, the nuchal plate 23 cm in length, and the entire headshield estimated at 40 cm.[1] According to the article cited, Dhanguura probably exceeded the contemporary Taemasosteus in size.[1]
Taxonomy
editDhanguura was thought to be a member of Homostiidae, according to Young, 2004, but a phylogenetic analyses by Zhu et al. 2015, does not support this, with Dhanguura now considered a basal brachythoracid.[2]
