Her M.S. was granted by the University of New Mexico in 2002 and her thesis topic was taphonomy and vertebrate paleontology of an Upper Triassic bonebed. Her Ph.D. was awarded by UNM in 2008 and her dissertation focused on the magnetostratigraphy of the Upper Triassic Chinle Formation. Kate now works to apply stratigraphic data sets to aquifer mapping and groundwater resource management projects in rural agricultural communities. William Parker has been employed as the lead paleontologist at Petrified Forest National Park in Arizona since 2001, where he established and leads the park's vertebrate paleontology research lab. Since 2002, park staff have published more than 50 papers on the geology and paleontology of the Triassic Period. Dr. Parker has 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. He is considered an expert in the study of Triassic archosaurian reptiles and on the geology and stratigraphy of the Upper Triassic Chinle Formation of Arizona.
