Formation Kaibab Limestone. Toroweap Formation Coconino Sandstone Hermit Shale Supai Group Redwall limestone (Temple Butte Ls) Muax Limestone Bright Angel Shale Tapeats Sandstone Tonto Group Basement: Vishnu. schists Rock's Type and Depositional Environment Fossils of corals and other reef building and dwelling organisms (crinoids, and brachiopods and nautiloids). Shallow water sandstone, Limestone and evaporites. Cross-bedded sandstone wind related. Fossils of reptiles. Red-colored sedimentary rocks with ripple marks and mud cracks. Contains poorly preserved plant fossils. Coastal Swamps. Both marine and non-marine deposits of mud, silt, sand, and calcareous sediments were laid down on a broad coastal plain with deltas. They represent transgression and regression. Fossils of amphibians and plants. Light-gray, thin-bedded, fine-to coarse-grained, cherty limestone on top of a conglomerate. The bottom is an unconformity. Composed of grey limestone separated by beds of sandstone and shale. Has fossils of trilobites and brachiopods. Mudstone with some layers of sandstone and shale from a platform. Few fossils of brachiopods and trilobite. Massive cliff-forming unit of brown sandstone. Much of the sand is very coarse-grained, often pea-sized or larger, represents a shore/sand bar deposit. A major unconformity c is found at the lower contact with the basement. These are the basement rocks. These are below the sedimentary rocks or sedimentary basins that are metamorphic or igneous in origin. Age Early-middle Permian Early Permian Early Permian Early Permian Late Mississippian to Early Permian. Above major unconformity Mississippian Cambrian 1.74-1.25 billion years Sea level changes T/R T T R Dominant environment Marine, Continental, Transitional Marine Marine/Transitional Continental
