The Chinle Formation is an Upper Triassic continental geological formation of fluvial, lacustrine, and palustrine to eolian deposits spread across the U.S. states of Nevada, Utah, northern Arizona, western New Mexico, and western Colorado.

Jun 13, 2015 · The Chinle Formation is best known from Petrified Forest National Park, where massive petrified conifer tree trunks are found in abundance, as well as a wide assortment of animals, including early dinosaurs such as Coelophysis.

Sep 13, 2020 · The Chinle Formation was deposited over 200 million years ago during the Late Triassic Period. The colorful badland hills, flat-topped mesas, and sculptured buttes of the Painted Desert are primarily made up of the Chinle Formation, mainly fluvial (river related) deposits.

Chinle Formation in north-central New Mexico, describes the Chinle Formation in the type locality in northeast Arizona, and discusses the correlation of units between those areas.

The Chinle formation is exposed in the Painted Desert of northern Arizona. The Chinle's colorful mudstones, and less abundant lenses of sandstone and conglomerate, were deposited by a large river system.

The Chinle Formation consists mostly of pastel-colored mudstones and siltstones punctuated by a few thin sandstone beds. It is known for stunning scenery in the candy-striped hills that make up the Painted Desert and in Petrified Forest National Park in northern Arizona, where large fossil logs are also found in great abundance.

The Chinle Formation consists of, in ascending order, the Shinarump, Mesa Redondo, sandstone and siltstone, Monitor Butte, Petrified Forest, Owl Rock, and Church Rock Members.

The Chinle Formation is an extensive geological unit in the southwestern United States, preserving a very diverse fauna of Late Triassic (primarily Norian -age) animals and plants.
