The petrified wood fossils, locally called Badyangon, were discovered in 2024 in Barangay Mina-utok, Calatrava, Negros Occidental. These fossils are estimated to be around 15 million years old and are believed to be remnants of ancient forests preserved through mineralization over time. The fossils are mostly large pieces of wood turned into stone, showing visible layers, cracks, and colors shaped by natural erosion. They are important for understanding ancient plant life and the environmental conditions of the Middle Miocene Epoch. The site remains protected, although no official conservation plan has been implemented yet.
