Thailand Discovers New Dinosaur With 66-Foot-Long Neck

Scientists in Thailand just added a spectacular new member to the dinosaur family tree, and this one stands out with a neck you have to see to believe.

Meet Uragasaurus kalasinensis, a plant-eating dinosaur that stretched 66 feet from head to tail and lived 150 million years ago. Its neck alone was extraordinarily long, perfectly designed for reaching vegetation at different heights across the ancient landscape.

Dr. Apirat Nilphanaphan from Mahasarakham University led the team that identified the new species from fossils discovered in Kalasin Province in northeastern Thailand. The breakthrough came from studying a single back bone that showed features never seen before in any dinosaur worldwide.

The discovery started back in 2008 when a local resident stumbled upon fragments that looked like serpent scales at a site called Phu Noi. When scientists excavated the area, they found a treasure trove of Late Jurassic fossils, with more than 90% being dinosaur remains.

The real excitement came when researchers performed a CT scan on a recovered vertebra. The scan revealed a Y-shaped arrangement of supporting bones and a unique air-cavity structure that set this dinosaur apart from every other species known to science.

This gentle giant belongs to the Mamenchisauridae family, a group of long-necked sauropods previously found almost exclusively in China. Thailand's discovery represents the first time this dinosaur family has been identified in the country, expanding our understanding of where these creatures lived millions of years ago.

Why This Inspires

This discovery proves that groundbreaking scientific finds can still happen when local communities and researchers work together. What began with one curious person noticing unusual fragments led to rewriting prehistoric history for an entire region.

Dr. Nilphanaphan's reaction captures the pure joy of scientific discovery. He was so overwhelmed with excitement upon confirming the new species that he smashed his keyboard, feeling both exhilarated and relieved that years of careful study had paid off.

The findings, published this week in the journal Nature, add to Thailand's growing reputation as a hotspot for dinosaur discoveries. Just months ago, scientists identified the nagatitan in Thailand, the largest dinosaur ever found in Southeast Asia at 88 feet long and weighing as much as nine adult Asian elephants.

Each new discovery reminds us that our planet still holds countless secrets waiting to be uncovered, inspiring the next generation of scientists to keep exploring.
