Paleontologists have discovered a new species of giant sauropod dinosaur in Thailand's Chaiyaphum province named Nagatitan chaiyaphumensis [1, 2, 3].
The discovery is significant because it represents the largest dinosaur ever found in Southeast Asia. This find provides researchers with new clues regarding how sauropods grew to enormous sizes and expands the existing knowledge of dinosaur diversity within the region [1, 3].
The animal lived approximately 100 to 120 million years ago [1, 3]. According to fossil measurements, the dinosaur reached a length of about 90 feet [4].
Estimates of the creature's weight vary slightly between reports. ScienceDaily said the dinosaur weighed around 27 tonnes [3], while an NPR summary estimated the weight at about 30 tons [1].
The fossils were uncovered in the Chaiyaphum province, where the team of researchers and paleontologists conducted their study [2, 4]. This discovery marks the 14th named dinosaur species found in Thailand [1].
Sauropods are characterized by their long necks and massive bodies. The scale of Nagatitan suggests that Southeast Asia supported megafauna comparable to those found in other parts of the world during the Cretaceous period [3]. Researchers said the find helps map the evolutionary trajectory of these giants across the prehistoric landscape [1, 3].
“the largest dinosaur ever found in Southeast Asia”
The identification of Nagatitan chaiyaphumensis fills a critical gap in the paleontological record of Southeast Asia. By proving that the region could support animals of this magnitude, the find suggests that the environmental and ecological conditions of prehistoric Thailand were more similar to other global dinosaur hotspots than previously understood.
