Description
Source: Wikipédia
The Almond Formation is a geological formation of Late Cretaceous (Late Campanian-Early Maastrichtian) age in Wyoming. It was deposited in marsh, deltaic, lagoonal, estuarine, and shallow marine environments along the western shore of the Western Interior Seaway. It consists primarily of fine- to medium-grained sandstone, siltstone, shale, and coal. Fossils from the Almond Formation include remains of dinosaurs and plants.
