I am a vertebrate paleontologist and biostratigrapher who primarily works in early Mesozoic rocks of the Colorado Plateau. I have B.S. and M.S. degrees in Geology from Northern Arizona University and a Ph.D. in Geology from the University of Texas at Austin. I have been the lead paleontologist at Petrified Forest National Park in Arizona since 2001.
