Dale Greenwalt is former biochemistry professor and current President of the Palaeontological Society of Washington. In this presentation, he will describe the Smithsonian’s efforts to collect and study fossil insects from 46-million year-old lake sediments now exposed along the Middle Fork of the Flathead River. The fossils themselves, unusually small and extremely well-preserved, include numerous new species of flies. This site, called the Kishenehn, may be the most productive site for fossil mosquitoes and wasps in the world as well as a new family of damselflies.
