Researchers have made an exciting discovery in Thailand. They’ve identified a new species of dinosaur called Nagatitan chaiyaphumensis, the largest ever found in Southeast Asia. This massive creature measured around 90 feet long and weighed approximately 30 tons, which is similar to over four African elephants.
Thitiwoot Sethapanichsakul, a Ph.D. student at University College London and lead author of the study, emphasizes the thrill of uncovering such a large dinosaur. The recent findings were published in the journal Scientific Reports.
Nagaititan roamed during the late Early Cretaceous period, about 100 to 120 million years ago. The discovery is significant as it showcases a notable evolutionary trend. While this dinosaur is massive, larger sauropods emerged later, with some weighing as much as 70 tons.
The fossils were first spotted by a local resident in 2016, but excavation paused due to a lack of funding. The work resumed in 2024, driven by renewed financial support. Researchers relied on vertebrae, ribs, pelvic, and leg bones to estimate its size. One notable bone, a front leg, was nearly six feet long.
Mathew Wedel, a paleontologist at Western University of Health Sciences, noted the quality of the fossil evidence. He described the material as promising and highlighted the information it can provide about sauropod anatomy.
The researchers have dubbed it the “last titan” of Thailand. According to Sethapanichsakul, the rock formation in which Nagatitan was discovered is the last destination for finding large dinosaurs in the country. He believes no further discoveries of this magnitude are likely in the region.
This finding opens new doors for understanding the ancient past of Southeast Asia. Each fossil discovery helps piece together the continent’s history and the evolutionary paths taken by these ancient giants. The excitement surrounding this research reflects a growing recognition of Southeast Asia’s importance in the paleontological landscape.
