Welcome to the Finnegan marine paleobiology group in the Department of Integrative Biology and the University of California Museum of Paleontology at the University of California, Berkeley. Research in our lab focuses on 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.  We integrate 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.
