Andrew Zaffos

I am a Senior Research Scientist at the Arizona Geological Survey and University of Arizona. My primary interest is the extinction and diversification of marine organisms. Specifically, I study how patterns of marine deposition and erosion controlled fossil biodiversity throughout the history of complex animal life. I also study the phenomena of niche conservatism and biogeographic conservatism in ancient marine biotas, at both regional and global scales. I am currently part of several geoinformatics initiatives - the Macrostrat Database, Paleobiology Database, the Rockd and Flyover Country social media applications, and the GeoDeepDive Library of machine-readable scientific documents - which are all working to increase the accessibility of geoscience data for the scientific community and general public.
