We have an active program that has had a recent focus on terrestrial ecosystems of North America. To learn more about specific research projects, click on the links below. To learn more about Smith Lab members, please visit our People page.
Some highlights of our current research:
Dena M. Smith
Dena Smith's research is broadly focused on insects in the fossil record. To study evolution, she works at multiple spatial and temporal scales--conducting both in-depth field-based research at targeted localities and large-scale literature based research across multiple geologic time intervals. She also conducts studies in modern ecosystems and in the lab in order to learn more about the specifics of plant-insect interactions and processes of fossilization.
Erin Leckey is interested in biological interactions through time, especially between plants and animals. Her research looks at specialized interactions between plants and animals in modern ecosystems, seeing how far back they can be tracked in the fossil record with a series of remarkable fossil deposits that span the last 50 million years of western North American terrestrial ecosystems.
Mary Ellen Benson
Mary Ellen Benson's research on the diatoms of the Eocene Florissant lake beds of Colorado is multifaceted, beginning with the taxonomy of some of the earliest modern flora in the fossil record, examining how these taxa fit into the evolutionary continuum, and considering what the diatoms in their sedimentologic and stratigraphic context might suggest about the paleolimnology of the ancient lake.
John Hankla's research involves vertebrate micro-fossils that are collected in the nests of the western harvester ant. By exploring the collecting methods of these ants, he is unraveling taphonomic factors associated with this unique type of fossil assemblage. John's field site is in an historic dinosaur quarry in the latest Cretaceous Lance Formation of Wyoming.
Jenell is interested in studying fossil insects and how their environments affect their preservation quality. She is working at the world famous Florissant Fossil Beds to study taphonomic processes and the preservation of fossil beetles, flies, wasps and true bugs.
Diane Brown's background is in veterinary clinical pathology. Her current research interests include marine invertebrates, including connections between past and present species. She is presently working with the Museum's extensive Burgess Shale collection.
Melissa Barton's thesis work focuses on late Eocene to late Oligocene fossil plants from localities in the Northern Rocky Mountains. The Eocene-Oligocene climate transition was a time of great ecological change as global climate cooled. Altered temperatures and weather patterns strongly affected both plant and animal communities. She hopes to learn more about the local timing and terrestrial effects of Eocene-Oligocene cooling in central Colorado.
Kevin Webster is currently working on the taphonomy and paleoecology of the arthropod-bearing concretions of the Barstow Formation of southern California. Previously, he worked on taphonomy and preservation biases of cephalopods and bivalves in the Pierre Seaway of Late Cretaceous Maastrichtian North America.
