Fossils
Fossil tracks of prehistoric animals have been discovered in the park at the Tat Yai waterfall area, which is part of the Huai Hin Lat Formation. They were first discovered in May 2023, and the first tracks discovered belonged to a sauropod. On 10 January 2024, a team of paleontologists from Thailand's Department of Mineral Resources discovered several more prehistoric footprints dating to the late Triassic period around 220–225 million years ago. Several of the footprints belong to dinosaurs, making them the oldest dinosaur tracks discovered in Thailand and Asia. The tracks are in good condition and show the details of the feet of five different species, including dinosaur types such as ornithopods, theropods, sauropods, and archosaurs.
