New dinosaur
Scientists say they’ve identified the largest long-necked, herbivorous dinosaur to ever live in Southeast Asia.
abcnews.comHere are the latest developments on dinosaurs in Thailand based on recent reports:
-
A massive new sauropod species, Nagatitan chaiyaphumensis, was identified in Thailand and described as one of the largest dinosaurs found in Southeast Asia. The specimen is estimated to be about 27 meters long and around 27 tonnes in weight, dating to roughly 100–120 million years ago. This finding has been reported by multiple outlets as of May 2026, highlighting its significance as potentially the last large sauropod remains discovered in the region.[1][3][8]
-
The discovery was announced after fossils were found in the Chaiyaphum province, with researchers suggesting the formation where it was uncovered represents a relatively young dinosaur-bearing layer, which contributes to its characterization as a possibly near-final giant of the Southeast Asian dinosaur record.[3][4][1]
-
Coverage notes that Nagatitan chaiyaphumensis is a long-necked herbivore (sauropod) and that its size makes it notable not only regionally but for comparisons with global sauropod diversity. Several articles emphasize the Thai-British collaboration and the study’s publication in Scientific Reports.[7][1][3]
-
In addition to the primary discovery, a number of outlets have framed the find within broader Southeast Asian paleontology, mentioning Thailand’s growing catalog of named dinosaur species and situating Nagatitan chaiyaphumensis as a landmark in the region’s dinosaur fossil record.[9][10][7]
If you’d like, I can summarize key findings from the main sources, or pull together a quick side-by-side with other Southeast Asian sauropods for comparison. I can also monitor for follow-up research or any new species announcements from the same formation. Would you prefer a concise summary or a detailed comparison table?
