The discovery of Nagatitan chaiyaphumensis, the largest dinosaur ever found in South-East Asia, is a testament to the power of curiosity and the importance of local knowledge. Thitiwoot Sethapanichsakul, a PhD student in palaeontology, has fulfilled a childhood dream by naming and describing this magnificent creature. What makes this discovery particularly fascinating is the role of a local villager, Thanom Luangnan, who first spotted the unusual bones sticking out of the ground. This highlights the value of amateur contributions to the field of palaeontology, which often relies on the keen eyes of passersby and locals. The story of Nagatitan is not just about the size of the dinosaur, but also about the evolution of sauropods and the changing world they inhabited. As the world was warming, these giants were pushed to get bigger and bigger, reaching sizes that allowed them to access resources that other dinosaurs couldn't. This raises a deeper question about the role of environmental changes in the evolution of species. The discovery of Nagatitan also has broader implications for the field of palaeontology in Thailand. It marks a shift towards a more inclusive and collaborative approach, with local researchers playing a central role in the discovery and description of new species. This is a refreshing change from the past, where teams from Europe would come in and excavate material, often naming it after Thai people but not including Thai researchers in the process. The opening of the Thainosaur Museum in Bangkok, with a life-sized reconstruction of Nagatitan as its centrepiece, is a symbol of this new era. It is a testament to the power of local knowledge and the importance of sharing scientific discoveries with the public. In my opinion, the discovery of Nagatitan is a dream come true for Thitiwoot Sethapanichsakul and a significant contribution to the field of palaeontology. It is a reminder that the pursuit of knowledge is a collaborative effort, and that the contributions of amateurs and locals are invaluable. As we continue to explore the past, it is important to remember the role of curiosity and the power of local knowledge in shaping our understanding of the world.
