Overview
- Researchers have formally described Nagatitan chaiyaphumensis in Scientific Reports, naming a new long‑necked herbivore from northeastern Thailand.
- The team estimates the animal weighed about 27 tonnes and measured roughly 27 meters, the largest dinosaur documented in Southeast Asia.
- Scientists assign it to Euhelopodidae, an Asian group of long‑necked dinosaurs, based on distinctive features in its spine, pelvis, and legs.
- Locals found the first bones in Chaiyaphum in 2016, work paused in 2020 when funds ran out, and a 2023 National Geographic grant enabled the study to conclude.
- The fossils come from Thailand’s youngest dinosaur‑bearing rocks, leading authors to call it the country’s “last titan,” while a life‑size model now draws visitors at Bangkok’s Thainosaur Museum.
