Overview
The Flaming Cliffs — known locally as Bayanzag — are among the most legendary fossil localities on Earth. During the American Museum of Natural History's Central Asiatic Expeditions of the 1920s, Roy Chapman Andrews' team found the first dinosaur nests and eggs recognized by science here, transforming our understanding of how dinosaurs reproduced. The cliffs glow orange-red at sunset, giving the site its name.
Geology
The fossils come from the Djadokhta Formation, ancient desert dune and interdune deposits. Sudden sandstorm or dune-collapse burial preserved animals in lifelike poses, producing some of the most complete and dramatic Cretaceous specimens known, including animals caught in the act of behavior.
What You See
Bayanzag is a remote desert destination of red sandstone cliffs and badlands, usually visited as part of a guided Gobi expedition. There are no displayed skeletons on-site — the famous fossils are in museums — but the landscape and its history draw travelers from around the world.
Famous Finds
Velociraptor and Protoceratops were both first described from this region, and nearby beds produced the celebrated 'Fighting Dinosaurs' specimen — a Velociraptor and Protoceratops locked together, apparently buried mid-combat. The egg discoveries here reshaped paleontology.
Visiting
Reaching Bayanzag requires a multi-day overland trip from Ulaanbaatar with a guide and prepared vehicles. Treat it as a wilderness expedition: there are no services at the site itself.
Best time to visit
May–September for accessible desert roads. June and September balance heat and crowds. Sunset at Bayanzag is the classic experience.
Getting there
Fly to Ulaanbaatar, then join a guided Gobi tour (typically 4–7 days) via Dalanzadgad. Bayanzag is ~100 km from Dalanzadgad over desert tracks — 4WD required.

Market & Provenance
Mongolian dinosaur fossils are state property. Tarbosaurus, Velociraptor, and Protoceratops from Mongolia on the commercial market are almost always illegal — multiple high-profile repatriation cases confirm this.
Collecting & Legality
Strictly blocked. Mongolian dinosaur fossils are state property and cannot be privately owned, collected, or exported — full stop. Smuggled Mongolian dinosaurs (including Tarbosaurus and Velociraptor) have been the subject of high-profile repatriation cases and prosecutions. Any Mongolian dinosaur material offered for sale is almost certainly illegal; do not buy it.
FAQ
Can I collect fossils in the Gobi?
No. Mongolian law makes all dinosaur fossils state property. Export is prohibited.
Where are the famous fossils now?
In museums — the AMNH, Mongolian Academy of Sciences, and others. None should be on the commercial market.
Is it safe to visit?
With a reputable guide and proper vehicle, yes — but this is remote desert travel, not a casual day trip.
