Giant new dinosaur identified from fossils in Thailand
The nagatitan is the largest dinosaur found in South-East Asia and weighs as much as nine elephants.
www.bbc.comHere’s the latest on dinosaurs in Thailand based on recent reporting.
Headline update
- A new giant long-necked dinosaur, Nagatitan chaiyaphumensis, has been identified from fossils found in Thailand. Early 2026 reports describe it as the largest sauropod known from Southeast Asia, with estimates around 27 meters in length and about 27 tons in weight. This discovery has been covered by multiple outlets in mid-May 2026, highlighting it as possibly the biggest dinosaur yet found in the region.
Key details
- Scientific significance: The find expands Thailand’s dinosaur record and positions Nagatitan chaiyaphumensis as a major late-Cretaceous sauropod in Southeast Asia, contributing to our understanding of dinosaur distribution in that region.
- Naming and origin: The species name references the Nagas of Southeast Asian folklore and the Chaiyaphum province where fossils were discovered, with locals originally spotting the bones in 2016.
- Context in regional discoveries: Thailand has a growing catalog of named dinosaur species, and this find is described as potentially the largest from the country and perhaps Southeast Asia.
What to watch next
- Further peer-reviewed publications and fossil material could refine measurements, growth stages, and ecosystem context for Nagatitan chaiyaphumensis. Expect follow-up papers and regional paleontological analyses over the coming months.
