The West Range Limestone is a geologic formation in Nevada. It preserves fossils dating back to the Devonian period.
Nevada is a state in the Western United States. It is bordered by Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the 7th most extensive, the 32nd most populous, but the 9th least densely populated of the U.S. states. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las Vegas–Paradise metropolitan area where three of the state's four largest incorporated cities are located. Nevada's capital is Carson City.
The Devonian is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, 419.2 million years ago (Mya), to the beginning of the Carboniferous, 358.9 Mya. It is named after Devon, England, where rocks from this period were first studied.
Paleontology in Nevada refers to paleontological research occurring within or conducted by people from the U.S. state of Nevada. Nevada has a rich fossil record of plants as well as both invertebrate and vertebrate animal life. During the Late Precambrian eastern and southern Nevada was being gradually covered by a shallow sea that was home to blue-green bacteria. During the early Paleozoic a variety of local aquatic invertebrates inhabited both freshwater (molluscs) and salt water (graptolites). By the Carboniferous reefs formed despite a drop in local sea levels and a variety of plants flourished on land.
