Scientists in Thailand have identified a previously unknown dinosaur species based on remains unearthed in Kalasin Province. Named Uragasaurus kalasinensis, this herbivore roamed the earth roughly 150 million years ago and reached lengths of 20 meters, comparable to a cricket pitch.
Lead researcher Dr. Apirat Nilphanaphan from Mahasarakham University noted the specimen was recovered from the Phu Noi site, which has been a rich source of Late Jurassic fossils since its discovery in 2008. The team identified the species after analyzing a distinct dorsal vertebra found at the location.
Advanced CT scans confirmed the creature belongs to the Mamenchisauridae family, known for their expansive necks used to browse high vegetation. This marks the first time a member of this family has been identified in Thailand, distinguishing it from related fossils found primarily in China. Analysis highlighted unique bone structures, specifically an air-cavity arrangement that researchers say is globally unique. The findings were officially published in the journal Nature.
