Overview
- The peer-reviewed paper in Scientific Reports, published Thursday, formally describes Nagatitan chaiyaphumensis.
- Researchers estimate the long‑necked herbivore exceeded 27 meters in length and weighed about 27 to 30 tonnes, the largest yet found in Southeast Asia.
- Local residents discovered the bones in Chaiyaphum in northeastern Thailand, and systematic excavation finished in 2024.
- The name draws on the Naga serpent from regional myth and the Chaiyaphum site, and a full‑scale reconstruction is on display at a Bangkok museum.
- The fossils date to 100 to 120 million years ago, which the team says makes this sauropod Thailand's “last titan” because younger rocks in the area record a shallow sea.
