Tha Chang

Geography

Tha Chang is part of Khorat Geopark, a plot of land at Lam Takhong river, part of cuesta (known locally as Khao-Meed-I-To). Fossils, especially primitive elephants were found, so it is an important international geopark. Khorat Geopark covers five districts of Nakhon Ratchasima, Sikhio, Sung Noen, Kham Thale So, Mueang Nakhon Ratchasima and Chaloem Phra Kiat. UNESCO certified it as the 2nd UNESCO Global Geoparks of Thailand and is the 4th place in the world in May 2023. Fossils of 10 genera out of 55 genera of elephant ever discovered on earth were found here. Four-tusked elephant, shovel tusker and stegodon are part of them. In addition, some extinct mammals have also been discovered here, such as Merycopotamus thachangensis. It was named to honour the subdistrict. Lam Takhong and Mun rivers are the lifeblood of the locals. Tha Chang is about northeast of Bangkok. Adjacent subdistricts are (from north clockwise): Nong Ngu Lueam in its district, Lam Mun in Non Sung district, Chang Thong in its district, Si Lako in Chakkarat district, Nong Yang in its district, Si Suk in Chakkarat district, and Phra Phut in its district.
