Cedar Mountain Formation, Geological formation in Colorado and Utah, United States
The Cedar Mountain Formation is a geological layer made of conglomerate, sandstone, and mudstone that extends hundreds of meters across the eastern region. These deposits formed during the Early Cretaceous period and hold many traces of ancient life.
The layer was first documented in 1944 by William Lee Stokes and named after Cedar Mountain in northern Emery County. This naming came during his systematic study of Early Cretaceous fossils in the area.
Scientists continuously study this formation to understand Early Cretaceous dinosaur distribution and evolution through numerous fossil discoveries within its layers.
The formations are located in protected areas and require permits for scientific visits. For casual visitors, marked viewpoints and educational trails offer insights into the geology.
The layer preserves two different dinosaur groups in its upper and lower sections, reflecting different living environments and conditions. This distribution lets researchers track how the ancient continent changed over time.
