A group of paleobiologists were studying sedimentary rocks in the Rocky Mountains of North America. What order of organisms would they find in the layers of these sedimentary rocks? All organisms are arranged randomly in the layers of sedimentary rocks./ Newest organisms are at the bottom and the oldest organism is in the top-most layer of the sedimentary rocks. /Oldest organisms are at the bottom and the newest organism is in the top-most layer of the sedimentary rocks.

Sedimentary rocks are rocks that are formed by the deposition of the weathered remains of other rocks. These are mixed sand, mud and pebbles that are laid down in layers and even fossils are found in these rocks. The order of organisms that they would find in the layers of these sedimentary rocks is, oldest organisms are at the bottom and the newest organisms are in the topmost layer of the sedimentary rocks.

The order of organisms that they would find in the layers of these sedimentary rocks is; Oldest organisms are at the bottom and the newest organism is in the top-most layer of the sedimentary rocks.

Sedimentary rocks are rocks that are made by the deposition and compression of other rocks or pieces of organic matter (dead plants and animals). According to the law of superposition which states that in a sequence of undisturbed sedimentary layers, the youngest layer is always at the top while the oldest layer is always at the bottom of the sequence. From the question, the organisms are components of the rocks. The oldest organisms will be found at the bottom layer of the sedimentary rocks while the newest organisms are in the topmost layer of the sedimentary rocks.
