Professor Stephen T Hasiotis

I study organism-media interactions and their implications for paleontology, sedimentology, stratigraphy, paleoenvironments, paleoecology, paleopedology, paleohydrology, and paleoclimate. My main research focuses on interactions in the continental realm, where organism activity relates to the history of the soil formation and the record of paleobiodiversity not recorded by body fossils in deposits where they are lacking. My interests include the distribution of trace fossils in the continental realm, evolution of organism behavior, evolution of continental ecosystems, the interpretation of past climates from paleosols, and effects of extinctions on soil biota and their recovery.
