Richard Barclay

Research Geologist

I am a paleobotanist who uses fossil plants to solve geological problems. I study deep-time fossil plant records, integrate those with high-resolution geochemical records, and work within temporally well-constrained sections to maximize the results of my efforts. My research interests focus on 4 main areas: 1) global carbon cycle perturbations; 2) paleoclimate change; 3) mass extinction events; and 4) species evolution and radiation.
