Lead author Tsogtbaatar Chinzorig from the Mongolian Academy of Sciences unearthed this remarkable skeleton in the Khuren Dukh locality of the Eastern Gobi Basin. This adolescent dinosaur would have weighed between 360kg and 408kg and stood about 2.1m tall, growing to around 4.3m in adulthood. The discovery of Z. rinpoche opens new avenues for research, enabling scientists to correlate dome development with growth stages more effectively than before. “The discovery of gastroliths, or stomach stones, alongside the recovered materials, reshapes our understanding of how pachycephalosaurs processed their food,” Chinzorig commented. As Z. rinpoche reinvigorates the conversation surrounding the evolution of this dinosaur group, the research team remains committed to further exploration and discovery.
