Scientists Identify 'Nagatitan,' Largest Dinosaur Ever Found in Southeast Asia

Scientists have officially identified a new species of giant sauropod dinosaur, named Nagatitan chaiyaphumensis, discovered in northeastern Thailand. According to a study published in the journal Scientific Reports, this long-necked herbivore measured approximately 27 meters in length and weighed around 27 tonnes, making it the largest dinosaur ever found in Southeast Asia. It lived between 100 and 120 million years ago, weighing at least 10 tons more than the famous Diplodocus known as 'Dippy.' The species was dubbed 'the last titan' by Thai doctoral student Thitiwoot Sethapanichsakul because it was unearthed in one of the youngest rock formations containing dinosaur fossils in the region, suggesting it may be the last giant sauropod to inhabit the area before it became a shallow sea. The initial remains were discovered by local residents a decade ago, with excavation completing in 2024. The name combines references to the mythical Naga serpent, Greek Titans, and Chaiyaphum province. A life-size reconstruction is currently displayed at the Thainosaur Museum in Bangkok.
