Paleozoic Bedrock Fossils. The 300-325 million year old Paleozoic limestones, sandstones, and shales that make up the sedimentary bedrock layers of the Mammoth Cave region formed in a depositional environment very different from what we see today. Limestone formed at the bottom of a shallow saltwater sea now known as the Mississippian Sea.The Precambrian was the "Age of Early Life."

Upstate New York, where PRI is located, hosts thick sequences ofThere is no definite date for the discovery of the first fossil fuel. According to the Kentucky Foundation, many ancient peoples used fossil fuels before they became popular as commercial sources of energy.The most important group within Phylum Cnidaria are the corals. Corals are multicellular animals that have a similar life habit to sea anemones. They are anchored to the ocean floor and precipitate a mineral framework around themselves which raises them up off the sea floor to more efficiently collect food. Each coral animal is known as a polyp.Therefore, their fossil remains can be used as an index or guide to that time, and consequently are called index fossils (Figures 7-2 and 7-3). For example, a marine animal called a trilobite lived only during the Paleozoic Era. Rocks containing trilobite fossils can be inferred to have been deposited during the Paleozoic.Ancient fossils preserved in the rock layers range from algal mats and microfossils from Precambrian Time 1,200 million to 740 million years ago to a multitude of body and trace fossils from the Paleozoic Era 525-270 million years ago.
