Nagatitan chaiyaphumensis, recently identified by researchers from Thailand and London, is the largest dinosaur ever discovered in Southeast Asia.
This remarkable creature, weighing around
27 metric tons (60,000 pounds), could stretch nearly
89 feet. Its name references a mythological serpent from Southeast Asian folklore, and it likely lived around
120 million to 100 million years ago during the late Early Cretaceous period.
Dr. Thitiwoot Sethapanichsakul, the lead researcher, noted,
"Our dinosaur is big by most people's standards — it likely weighed at least 10 tons more than Dippy the Diplodocus." The dinosaur was unearthed from a region in northeastern Thailand, with its skeletal remains found during fieldwork conducted between 2016 and 2019. Excavation efforts resumed in
2024 to complete the analysis. The discovery was made by local residents who found the humerus bone of the dinosaur, which measures
1.78 meters (almost six feet) long, on the bank of a communal pond during the dry season.
Sethapanichsakul believes Thailand boasts one of the
highest diversities of dinosaur fossils in Asia, aided by the thick layers of sedimentary rocks from the Mesozoic Era. He refers to Nagatitan as “the last titan” because it was found within one of the youngest rock formations where dinosaurs exist.
Overall, the discovery adds a significant chapter to the dinosaur history of Southeast Asia, highlighting both its unique biodiversity and the importance of ongoing paleontological efforts.

This discovery marks a significant addition to Southeast Asia's dinosaur history, with estimates suggesting it could weigh as much as nine adult elephants.
