Paleontology in Wyoming refers to paleontological research occurring within or conducted by people from the U.S. state of Wyoming. The fossil record of Wyoming spans from the Precambrian to recent deposits. There are a large number of different fossil sites spread throughout the state. Wyoming is such a spectacular source of fossils that author Marian Murray noted in 1974 that "[e]ven today, it is the expected thing that any great museum will send its representatives to Wyoming as often as possible." Murray has also written that nearly every major vertebrate paleontologist in United States history has collected fossils in Wyoming. Wyoming is a major source of dinosaur fossils. Wyoming's dinosaur fossils are curated by museums located all over the planet.
