New fossil reveals 88-foot dinosaur that once roamed Southeast Asia.

Scientists have uncovered evidence of a colossal dinosaur that once stalked Southeast Asia 120 million years ago.

Named Nagatitan chaiyaphumensis, this sauropod dwarfed modern transport, measuring 88 feet in length.

Its massive frame weighed approximately 27 tonnes, rivaling the combined mass of nine Asian elephants.

This discovery marks the largest dinosaur ever identified within the Southeast Asian region.

The fossilized remains were initially spotted a decade ago by a local resident near a pond in Chaiyaphum.

Researchers have since carefully excavated sections of its spine, ribs, pelvis, and a front leg bone comparable to human size.

Dr. Thitwoot Sethapanichsakul from University College London described the animal as a gentle giant.

Due to its immense scale, it likely faced few predators while browsing vegetation high in the canopy.

"It acted as a mega herbivore, consuming vast amounts of plant matter with minimal chewing," he explained.

The ancient landscape differed significantly from today's humid tropics, featuring arid forests and shrublands.

The site also hosted a meandering river system populated by fish, crocodiles, and freshwater sharks.

Despite sharing the land with fierce carnivores like Carcharodontosaurus, the Nagatitan remained safe from harm.

Even the largest predators, reaching only 26 feet, could not match the dinosaur's sheer bulk.

Professor Paul Upchurch noted that global temperatures rose sharply between 115 and 95 million years ago.

Scientists believe these massive creatures utilized their long necks and tails to manage body heat effectively.

Their ability to thrive in warming climates suggests they were uniquely adapted to changing environmental conditions.

New fossil discoveries reveal a massive sauropod dinosaur that dominated Thailand nearly 95 million years ago. Lead researcher Thitiwoot Sethapanichsakul notes these creatures grew to super gigantic sizes weighing around 70 metric tonnes. This trend allowed them to become some of the most successful species during the Early Cretaceous period.

Although the exact connection remains not fully understood, this specific find offers researchers a glimpse into early stages of this evolutionary process. Even though Nagatitan dominated its own habitat, it would have looked relatively puny compared to other giants from this period. Mr Sethapanichsakul explains that when compared to other sauropods, this species ranks in the upper middle of the size range.

True super giants existed in the middle Cretaceous of South America, China, and probably North Africa with body masses exceeding 60 tonnes. From the outside, Nagatitan would have looked very similar to its larger cousins with a long neck and tail, column-like legs, and a tiny head. However, scientists spotted unique characteristics in its legs, hips, and spine that mark it out as a unique species.

Based on the presence of teeth and scales, scientists think Nagatitan would have shared its environment with many other dinosaurs, fish, crocodiles, and sharks. This giant would have dwarfed them all despite its impressive stature. Nagatitan belonged to a subgroup of sauropods with bones that contained lots of internal air sacs and thin walls, making their skeletons lighter.

This group emerged about 140 million years ago, spread all over the world and, around 90 million years ago, became the only sauropods left worldwide. They held on until the dinosaur age ended 66 million years ago. Its scientific name, Nagatitan chaiyaphumensis, is a reference to the Naga, a mythological serpent often depicted in South-East Asian mythology and often connected with water.

Its specific name of chaiyaphumensis pays homage to the fact that the fossils were found in Chaiyaphum province, Thailand, according to Mr Sethapanichsakul. While the moniker titan refers simply to the dinosaur's enormous size, it is fitting as researchers refer to the animal as Southeast Asia's last titan.

Sometime after this specimen lived, Thailand was submerged by a shallow sea, which may have driven out the dinosaurs. Professor Upchurch states that although animals like this continue to live elsewhere in the world, large portions of Southeast Asia may have been flooded by sea level rise afterwards. Consequently, it might not have been possible for these animals to have lived there much after the time of Nagatitan.
