The remains were found on February 27, 1996 by volunteer Nicole Evered during excavations as part of the Dinosaur Dreaming Project, organized by Monash University and the National Museum of Victoria. The species Quantassaurus intrepidus was described in 1999 by the spouses Patricia Vickers-Rich and Tom Rich. The name of the genus is given in honor of the airline QANTAS . The species name intrepidus means “fearless” in Latin, referring to the habitat of animals in a cold climate [2] .
Qantassaurus was a herbivorous dinosaur that moved on two legs. Gregory S. Paul in 2010 estimated a length of 2 meters and a weight of about 12 kilograms.
The genus was assigned by the Rich spouses to the Hypsilophodontidae family [2] . In 2004, Norman et al. Transferred Qantassaurus to the Euornithopoda treasure [3] , and in 2010, Agnolin et al., In a phylogenetic analysis of Australian and New Zealand dinosaurs, established that the genus occupies a basal position in the ornithopod infraorder [4] .
