Ulansuhai Formation, Geological formation in Inner Mongolia, China
The Ulansuhai Formation is a geological layer in Inner Mongolia consisting of clay and silt deposits from the Cretaceous period. The site contains fossils of various ancient animals preserved within these rock layers.
The formation developed approximately 92 million years ago during the Cretaceous period in a shallow marine or lake environment. Clay and silt accumulated over time, preserving the remains of animals that inhabited this ancient landscape.
The formation holds importance for paleontologists studying ancient life, as it preserves remains of dinosaurs, turtles, and other creatures from that era. These discoveries help researchers understand how creatures lived and adapted long ago.
The site is located in a remote area of northern Inner Mongolia and requires proper preparation and local guidance to explore safely. Visitors should expect harsh conditions and limited facilities in the region.
Multiple dinosaur skeletons were discovered here at different growth stages, offering rare insights into how these animals developed from youth to adulthood. This collection reveals patterns of growth that are uncommon to find in fossil records.
