AI Insight
Researchers in Thailand have identified a new sauropod dinosaur species, Nagatitan chaiyaphumensis, estimated to have weighed approximately 27 tonnes and lived over 100 million years ago during the Cretaceous period. The animal belonged to the long-necked sauropod group and represents the largest dinosaur yet documented from Southeast Asia. Scientists hypothesize it may have been among the final large sauropods to inhabit the region before geological and sea-level changes reshaped the landscape.
Why it matters
This discovery expands the known diversity of large dinosaurs in Southeast Asia, a region historically underrepresented in paleontological research, and contributes to understanding how sauropod populations distributed and declined across different continental zones during the Cretaceous.
Understand the Science
A massive new dinosaur discovered in Thailand is rewriting Southeast Asia’s prehistoric history. The newly named Nagatitan chaiyaphumensis was a colossal long-necked sauropod that weighed around 27 tonnes and lived more than 100 million years ago. Scientists believe it may be the last giant sauropod ever to roam the region before rising seas transformed the landscape.
