Researchers Identify New Giant Dinosaur Species in Thailand

Researchers have identified a new species of giant long-necked dinosaur from fossils discovered in Chaiyaphum province, northeastern Thailand. The dinosaur, named Nagatitan chaiyaphumensis, is described as the largest of its kind found in Southeast Asia.

A Thai PhD student at University College London led the study. The student stated that the fossils represent the last known remains of this type of dinosaur in Thailand.

Local residents found the first fossils in 2016 along a rock formation near a pond. Excavation stopped in 2020 when funding ended. Work resumed after a 2023 grant from the National Geographic Society allowed researchers to complete the analysis.

Scientists estimate the dinosaur weighed approximately 27 tons.

The animal lived during the Cretaceous period between 100 and 120 million years ago. The species name combines a term from Southeast Asian folklore with a reference to Greek mythology and the province where the fossils were found. The student noted that Thailand has studied dinosaurs for only about 40 years.

The discovery is being used to increase public interest in paleontology through outreach programs.
