Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have …Limestone is a non-clastic sedimentary rock consisting of more than 50% calcite (a calcium carbonate mineral, CaCO3). Limestone is mostly a biological rock that forms in clear, warm, and shallow marine waters. Limestone exists in various types and colors.

The Redwall Limestone has a gray color, but almost everywhere it is stained red by iron oxide washed from the red, iron-rich layers above (Supai and Hermit Formations).How do fossils form? Fossils are formed in many different ways, but most are formed when a living organism (such as a plant or animal) dies and is quickly buried by sediment (such as mud, sand or volcanic ash). Soft tissues often decompose, leaving only the hard bones or shells behind (but in special circumstances the soft tissues of …Basically marble (proper) is limestone buried deep and cooked. And by deep I mean really deep. Some marbles from the Alps are known to come from more than 100 kilometres deep!

The youngest rock layers are at the top of the canyon, while the oldest are at the bottom, which is described by the law of superposition. Distinctive rock layers, such as the Kaibab Limestone, can be matched across the broad expanse of the canyon. We know these rock layers were once connected, which is described in the rule of lateral continuity.The Menard Limestone is composed of several layers, 15 to 45 ft thick, of dark argillaceous skeletal limestone separated by somewhat thinner zones of calcareous, fossiliferous shale and siltstone. The Menard is commonly 100 to 140 ft thick and is overlain by 30 to 90 ft of sandstone, siltstone, and shale assigned to the Palestine Sandstone. ….

Rock layers are also called strata (the plural form of the Latin word stratum ), and stratigraphy is the science of strata.

It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world.
