TIME FILE: Flaming Cliffs Formation - Mongolia, 80 million years ago

"The burning sands of a desolate kingdom"
(based on the Flaming Cliffs Formation)

Description
The climate here is a hot desert. The only sources of water and green come from sheltered oasis' between massive rolling dunes of sand.

Geography
The dunes are constantly on the move, making the ecosystem for water and food sources precarious at best. Large dunes are to the west, protecting a portion of the east well enough. Massive rainstorms periodically visit the desert, turning sand loose and creating massive sandslides capable of burying animals alive.

Features
Swampy lowlands, lakes, rivers and floodplains

Rock Type
Sandstone and limestone

Fossilisation Extent
Found mostly in sandstone, often individuals are in the poses they died in to the sudden nature of being buried alive in sand.
