For organic geochemists and paleobiologists who study biomolecules preserved in fossils and sediments, the 15th Annual Goldschmidt Conference could not have picked a better venue than Moscow, Idaho. Only 55 miles away from the conference site lies the middle Miocene Clarkia fossil deposit, which has become an icon for this emerging field of interdisciplinary research. In the past 25 years the Clarkia material has attracted worldwide attention through its preservation of ancient biomolecules and isotopic signals, generating both excitement and controversy.
