Paleontologists from Thailand and Japan identified a new species of giant long-necked herbivorous dinosaur named Nagatitan chaiyaphumensis in northeastern Thailand.
The discovery marks a significant milestone in Asian paleontology because the creature is the largest dinosaur ever found in Southeast Asia. Its unique skeletal features distinguish it from other known species, providing new insights into the prehistoric biodiversity of the region.
Researchers unearthed the fossils in the Chaiyaphum province [1]. The team estimated the animal reached a length of about 30 meters [2]. According to the study, the dinosaur's mass was approximately nine adult elephants [1].
"This is the largest dinosaur ever found in Southeast Asia," said Dr. Varavudh Suteethorn, the lead author of the study [1].
The identification follows an extensive dig and analysis of the skeletal remains. The researchers said that the sheer scale of the specimen is unprecedented for the region.
"The size of this animal, comparable to nine adult elephants, is truly astonishing," said co-author Prof. Hiroshi Yamamoto [2].
The discovery was officially announced in March 2024 [2]. The findings suggest that Southeast Asia supported massive sauropod populations, challenging previous assumptions about the distribution and size of giant herbivores in the area.
“"This is the largest dinosaur ever found in Southeast Asia,"”
The identification of Nagatitan chaiyaphumensis shifts the understanding of prehistoric ecosystems in Southeast Asia. By establishing that the region could support animals of this magnitude, scientists can now better analyze the food sources and environmental conditions that allowed such massive herbivores to thrive in the area.
