Petrified Wood Museum, Ancient Elephants, and Dinosaurs

The Petrified Wood Museum, Ancient Elephants, and Dinosaurs sits on Mittraphap-Nong Pling Road in Suranari Subdistrict, about 15 km from central Korat. It’s one of only seven museums in the world built specifically around large petrified wood specimens, and the biggest such collection in Asia — fossilised logs here run from around 800,000 to 320 million years old. The museum opened in 2008 and is split into three linked buildings: petrified wood, ancient elephants, and dinosaurs.

The petrified wood hall centres on a garden laid out to echo the Mun-Chi River Basin landscape that once covered this part of Isan, plus a short film covering the earth’s early history and the rise of life on it. Many of the logs on display were uncovered locally — including specimens exposed during gravel quarrying for the Mittraphap Highway around Khok Kruat and Suranaree, the same finds that helped build the case for Korat’s UNESCO Global Geopark designation, awarded in Paris on 17 May 2023.

The elephant building holds one of the richest prehistoric elephant fossil records found anywhere in Thailand, spanning several extinct genera including four-tusked and shovel-tusked forms alongside more familiar trunked ancestors. Alongside them are fossils of giant turtles, crocodiles, and early apes with a direct line to human evolution. The dinosaur hall rounds things out with life-sized replicas of species that once roamed northeastern Thailand.

The single piece most visitors remember afterward is a large petrified log of makha mong wood (Afzelia xylocarpa) — cut, polished, and coated so its cross-section shows the same banding and colour variation you’d expect from a cut gemstone rather than fossilised timber. It’s displayed as the centrepiece of the petrified wood hall and is one of the pieces most often used to represent the collection in Korat’s tourism material.

Insider Tip: Go early — the buildings aren’t air-conditioned throughout, and the petrified wood garden outside gets uncomfortably hot by midday in the hot season.

Watch out: It’s closed Mondays and sits away from the main tourist strip in central Korat, so it works best as a half-day trip combined with something else rather than a stand-alone stop.

For a broader look at Korat’s history, Nakhon Ratchasima City Museum and the Thao Suranari Monument are both closer to town and worth pairing with a visit here.
