Thailand's Nagatitan: a colossal sauropod bigger than Diplodocus

Researchers announced the discovery of Nagatitan chaiyaphumensis, a 27-meter, ~27-ton sauropod unearthed in northeastern Thailand and dating to about 100–120 million years ago. Described in Scientific Reports, it reportedly surpasses Diplodocus in size and stands as Southeast Asia's largest dinosaur fossil find to date; a life-size reconstruction is on display at Bangkok's Thainosaur Museum, with a Thai doctoral student nicknamed it 'the last titan' during the research.

Thailand Unveils Southeast Asia’s Largest Dinosaur Ever Found

Thai researchers and UCL collaborators describe Nagatitan chaiyaphumensis, an Early Cretaceous sauropod about 27 meters long and ~28 tons—the largest dinosaur yet found in Southeast Asia—discovered in 2016 in Thailand’s Khok Kruat Formation; bones include eight vertebrae, ribs, pelvis parts, a humerus and a femur, with 3D surface scanning used to model the specimen for study, and the species name honors the Naga myth and Chaiyaphum province; the study, published in Scientific Reports (2026), notes it may be among the last giant sauropods in the region, though heavier giants like Patagotitan exceed it.

Thailand Pond Find Unmasks Nagatitan: Southeast Asia’s Largest Sauropod

A 2016 discovery of unusually large bones along a dried pond edge in Chaiyaphum, Thailand, led to a decade of excavations and analysis that culminated in May 2026 with the identification of a new sauropod species, Nagatitan chaiyaphumensis. Weighing about 27 tonnes and 27 meters long, it is the largest dinosaur found in Southeast Asia, living in the Early Cretaceous (~100–120 million years ago) and likely representing the last of its kind in the region. The skull was not recovered, and the name honors local culture (Naga) and the discovery site (Chaiyaphum).

Thailand Unveils 90-Foot Sauropod Nagatitan: Southeast Asia's Largest Dinosaur

Thai researchers announce Nagatitan chaiyaphumensis, a roughly 30-ton, 90-foot-long sauropod—the largest dinosaur found in Southeast Asia—providing new insights into Early Cretaceous gigantism; fossils include multiple bones (spine, pelvis, ribs, legs) and a front leg bone nearly 6 feet long, with excavations continuing.

Thailand’s Last Titan: Nagatitan, the Largest Southeast Asian Sauropod

Scientists in northeastern Thailand identified a new giant sauropod, Nagatitan chaiyaphumensis, estimated to be about 88 feet long and 27 tons—potentially the largest dinosaur found in Southeast Asia—dating to roughly 100–120 million years ago. Discovered by locals, with excavation completed by 2024, the species earned the nickname “the last titan” and is now featured as a life-size reconstruction at Bangkok’s Thainosaur Museum after a study published in Scientific Reports.

Thailand Uncovers Southeast Asia’s Biggest Sauropod

In northeastern Thailand, researchers uncovered skeletal remains of Nagatitan chaiyaphumensis, a massive sauropod about 90 feet long and weighing roughly 25–28 tons, dating to ~113 million years ago. The find highlights Southeast Asia’s sauropod diversity and paints a picture of a subtropical, riverine ecosystem with predators and other dinosaurs, expanding understanding of how these giant herbivores lived and why they grew so large.
