Julia Clarke is an assistant professor in the Department of Marine, Earth and Atmospheric Sciences at North Carolina State University, a curator of paleontology at the North Carolina Museum of Natural Sciences, and a research associate in paleontology at the American Museum of Natural History. Her research interests include the timing and pattern of the origin of the lineages of extant birds and, more broadly, the systematics of Dinosauria and the evolution of flight. She serves on the editorial board of the Journal of Anatomy and is actively engaged in field work in Mongolia, China and Peru.
Ian M. Miller, Mark T. Brandon and Leo J. Hickey. 2006 May 15. Using leaf margin analysis to estimate the mid-Cretaceous (Albian) paleolatitude of the Baja BC block. Earth and Planetary Science Letters 245(1–2):95–114. doi:10.1016/j.epsl.2006.02.022.
Ian Miller first discovered geology in rural Washington while scavenging mine tailings for fool’s gold and pulling clams out of road cuts. He is currently working on his thesis, a treatise on paleobotanical proxies for paleolatitude, and is now a postdoctoral fellow at the Denver Museum of Nature and Science. His principle interests are in paleobotanical proxies for, and statistical analysis of, paleoclimate, paleolatitude and paleoelevation; the evolutionary history and ecological radiation of Cretaceous angiosperms; taxonomic analysis and nomenclature of whole Late Mesozoic floras; and tectonic evolution of the Western Cordillera of North America.
