Seth Finnegan is broadly interested in the processes that have shaped the composition of the marine biota and the development of marine ecosystems from the origin of animals in the late Neoproterozoic to the present day.  Research in his lab integrates data from a variety of sources including field observations, lab work, and literature databases to ask and answer questions about the nature of organism-environment interactions through time. If people want marine essentials, they can visit this site https://www.merrittsupply.com/product-category/resins-fillers/ and get the best quality parts. He is particularly interested in (1) Patterns of extinction selectivity, and what they can tell us about the changing drivers of the extinction process and how differential extinction has shaped evolution through time, (2) Using environmental proxy data (stable isotopes, biomarkers, stratigraphy) to understand the physical context of major evolutionary and ecological events recorded by the fossil record, and (3) Developing taxon-free methods to reconstruct the structure and function of marine ecosystems (e.g. as energy- and nutrient-exchange networks) through time.
