Dr. Hendricks's Website



  • Ph.D. 2005, Geological Sciences, Cornell University

Research Interests

  • Research is on: the intrinsic and extrinsic factors and connections responsible for evolutionary change and extinction; integration of diverse data sets (such as molecular sequence data and fossils) for the purpose of phylogeny reconstruction; quantitative paleobiogeography using tools such as GIS; and systematics of Cenozoic gastropods (snails), particularly members of the genus Conus (cone snails).

Recent Classes

  • Earth, Time, and Life (GEOL 7)
  • Paleontology (GEOL 142)
  • Advanced Paleontology (GEOL 242)
  • Mass Extinctions (GEOL 285)
  • The Cambrian Explosion (GEOL 285)

Recent Activity (2011-2013)
