Thailand Unveils Remarkable New Dinosaur Species with Exceptionally Long Cervical Region

New dinosaur species with neck as long – Scientists working in Thailand have announced the identification of a previously unknown dinosaur species, based on fossil evidence unearthed in the Kalasin Province of the nation’s northeastern region. This herbivorous creature, officially designated as Uragasaurus kalasinensis, roamed the Earth approximately 150 million years during the Late Jurassic epoch. The animal possessed a notably elongated neck and could reach lengths of up to 20 meters, which translates to roughly 66 feet—comparable to the span of a standard cricket pitch.

Historical Context of the Discovery Site

The fossil that ultimately revealed this new species was part of an extensive collection gathered from a location initially recognized in 2008. According to Dr Apirat Nilphanaphan, the lead researcher from Thailand’s Mahasarakham University who presented findings to BBC Thai, a local resident originally discovered fragments that resembled the scales of serpents at this site. The area, known as Phu Noi, has since proven to be exceptionally rich in Paleontological treasures spanning the Late Jurassic period.

Excavations at Phu Noi have yielded an impressive array of prehistoric remains. More than ninety percent of all fossils extracted from this particular location consist of dinosaur fragments. When researchers returned to conduct further surveys, they uncovered additional specimens including dinosaur teeth and various skeletal elements. However, the pivotal discovery came in the form of a dorsal vertebra—a bone situated in the middle or upper back region—that exhibited unique morphological traits distinguishing it from known species.

Scientific Analysis and Classification

Advanced CT scanning technology provided crucial insights into the anatomical structure of the fossil. The analysis confirmed that this dinosaur belonged to the Mamenchisauridae family, a group of sauropod dinosaurs renowned for their extraordinarily extended necks. These elongated cervical regions likely enabled the creatures to access vegetation at varying elevations without needing to move their entire bodies. While the majority of Mamenchisauridae fossils have historically been discovered within Chinese territories, this represents the first such finding documented in Thailand.

The scanning process also uncovered distinctive structural features, most notably a Y-shaped configuration of supporting bones called laminae. These architectural elements contributed to the strength and flexibility of the neck structure. Dr Nilphanaphan emphasized the significance of these characteristics when speaking with BBC Thai, noting that certain features, particularly an unusual air-cavity formation, distinguished this specimen from all other known dinosaurs globally.

“That’s what sets it apart,” Dr Nilphanaphan explained regarding the unique characteristics observed in the fossil. “The features, in particular a unique air-cavity structure, were unlike any other dinosaur in the world.”

Personal Reaction and Broader Significance

The moment of realization brought considerable emotion to the research team. Dr Nilphanaphan recounted how he smashed his keyboard upon understanding that they had identified a completely new species. He described experiencing simultaneous feelings of exhilaration and relief, reflecting both the excitement of discovery and the validation of years of dedicated research. The comprehensive study documenting this finding was published in the prestigious Nature scientific journal earlier this week.

This announcement follows another significant paleontological discovery made in Thailand during May. Scientists had previously identified a different type of long-necked herbivorous dinosaur called the nagatitan, based on remains excavated from Thai soil. The nagatitan holds the distinction of being the largest dinosaur ever discovered in South-East Asia. Weighing an impressive 27 tonnes—equivalent to the combined mass of nine adult Asian elephants—the creature measured 27 meters, or 88 feet, in total length.

Implications for Paleontological Research

The discovery of Uragasaurus kalasinensis adds valuable information to our understanding of dinosaur distribution and evolution during the Mesozoic era. The presence of Mamenchisauridae fossils in Thailand suggests that these long-necked herbivores had a broader geographic range than previously understood. The rich fossil deposits at Phu Noi continue to attract researchers from around the world, contributing to our knowledge of prehistoric ecosystems.

Additional reporting for this article was provided by Jiraporn Srijaem, who has covered various paleontological developments in the region. The ongoing discoveries in Thailand highlight the country’s importance as a site for understanding dinosaur biodiversity and the environmental conditions that existed millions of years ago. Beaches and excavation sites across the nation have proven particularly fruitful for fossil hunters and scientists alike.

These findings join other notable dinosaur discoveries from Thailand, including a “punk rock” species characterized by metre-long spikes that was identified from fossil remains. Each new discovery helps paint a more complete picture of the diverse prehistoric life that once thrived in what is now Southeast Asia, offering insights into evolutionary patterns and ecological relationships that shaped the ancient world.
