New Species of Long-Necked Dinosaur Identified in Thailand
Researchers said the find broadens mamenchisaurid diversity outside China and is based on a single vertebra that helped identify a new genus and species.
- Researchers including Dr. Apirut Nilpanapan of Mahasarakham University announced the discovery of Uragasaurus kalasinensis in a study published Wednesday, July 8, 2026, in the journal Scientific Reports.
- This mamenchisaurid species, the first formally named in Thailand, challenges previous understandings that this group of long-necked sauropods was almost exclusively restricted to East Asia.
- Catalogued as PRC 460, the anterior dorsal vertebra features a honeycomb-like internal structure that helped reduce the giant animal's bone weight around 150 million years ago.
- The find links Thailand's Phu Noi vertebrate assemblage to fossil faunas in China's Junggar and Sichuan basins, confirming the region was part of a wider, connected prehistoric landscape.
- Ongoing excavations in the Phu Kradung Formation may offer further insights into how these massive sauropods diversified and dispersed across prehistoric Southeast Asia during the Late Jurassic period.
