Remains of 'The Last Titan,' Largest Dinosaur in Southeast Asia, Discovered in Thailand

An international team of paleontologists has discovered the remains of Nagatitan chaiyaphumensis, a new species of giant dinosaur in Thailand, marking the largest dinosaur ever recorded in Southeast Asia. Nicknamed 'the last titan,' this long-necked sauropod lived approximately 120 million years ago during the Lower Cretaceous period. The specimen measured nearly 30 meters in length and weighed 27 tons, equivalent to nine adult elephants. The discovery was made in the Chaiyaphum province after an eight-year excavation effort spanning from 2016 to 2024, involving researchers from University College London, Mahasarakham University, Suranaree University, and the Sirindhorn Museum. Published in Scientific Reports, the study highlights that this creature likely represents the last large sauropod in the region before the area transformed into a shallow sea. The fossils, including spine, ribs, and leg bones, were found in Ban Pha Nang Sua. This finding underscores Thailand's significant role in paleontology, possessing the third most abundant dinosaur fossil diversity in Asia.
