A Chance Encounter Along a Dry Stream

What began as a routine family holiday to northeastern Thailand has culminated in a significant paleontological find. Authorities have officially confirmed the discovery of six fossilised dinosaur footprints dating back approximately 120 million years, thanks to a sharp-eyed tourist who snapped a photograph of unusual rock markings.

The discovery unfolded at Phu Phrabat National Park in Udon Thani province. While visiting a nature trail with his family, 32-year-old Thai tourist Pichai Prathetsena noticed peculiar indentations near a partially dried-up stream. The low water levels had exposed bedrock bearing the distinct impressions. Although pressed for time and unable to notify park rangers immediately, Prathetsena captured the marks on his camera and uploaded the image to a public social media group to seek opinions from fellow users.

The post quickly caught the attention of Thailand's Department of Mineral Resources (DMR), which initiated an immediate investigation. Park rangers were dispatched to the site on October 19 to conduct preliminary inspections and take measurements before dispatching a specialized team of paleontologists.

Scientific Significance of the Phu Phan Formation

Following a thorough on-site analysis, government experts verified that the impressions are genuine trace fossils.

"The find includes a single trail with a total of six prints on the Phu Phan formation, dating back approximately 120 million years to the Early Cretaceous period," representatives from Thailand's Department of Public Relations stated.

Measurements taken by researchers indicate that each footprint spans roughly 29 centimeters in length and 26 centimeters in width. Based on these dimensions, biometric calculations suggest the creature stood approximately 1.42 meters tall at the hip and measured about 6.3 meters in total length. Experts note that these dimensions closely match those of Siamotyrannus isanensis, an extinct theropod species previously unearthed in Thailand from the same geological epoch.

Theropods were a diverse group of two-legged, primarily carnivorous dinosaurs that included iconic predators such as the Tyrannosaurus rex.

Protecting a Prehistoric Legacy

In response to the confirmation, Thai authorities have moved swiftly to safeguard the site from potential vandalism, unauthorized excavation, and natural degradation. Access to the immediate area has been temporarily restricted under the provisions of Thailand's Fossil Protection Act 2008.

The Department of Mineral Resources is currently collaborating with the Department of National Parks, Wildlife and Plant Conservation, as well as the Fine Arts Department, to establish a permanent protective perimeter. Measures to mitigate water erosion and preserve the integrity of the trace fossils are also underway.

Government officials have emphasized that unauthorized individuals are strictly prohibited from entering the restricted zone, digging, or disturbing any geological evidence in the area. Subject to ongoing scientific assessments and long-term preservation planning, authorities intend to evaluate whether the site can eventually be developed into an educational and eco-tourism attraction for the public.
