Hagerman Fossil Beds National Monument

Julie A. Meachen is a pathbreaking vertebrate paleontologist and morphologist who studies mammalian carnivores and megafauna from the late Pleistocene period (10,000 years ago) to the present day.

Fossils at Hagerman Fossil Beds National Monument give off radon, a radioactive gas, which has plagued its collection storage since 1988. Hourly monitoring in a new building showed how to clear the air.
