Curating The Green River Plant Collection
Curating The Green River Plant Collection
Over the last four decades, Lance Grande, Curator Emeritus of Fossil Fishes, has led many excavations to sites in the Green River Formation in Wyoming, amassing a huge number of ~52-million-year-old fossil fish and other vertebrates, invertebrates, and plants.
- With support from the EAF’s NSF program, University of Oklahoma PhD student Pierce Wright investigated the coalescence of Choctaw communities in the 18th century via LA-ICP-MS ceramic analysis, as reported in Journal of Archaeological Science: Reports.
- In another article in the same journal, Lambert et al. analyzed a single copper bead using LA-ICP-MS to show how a late Archaic community in Southern Mississippi established long distance connections to obtain this object manufactured from copper from the Great Lakes region
- In an article in American Antiquity, Stevenson et al. studied copper object compositions via LA-ICP-MS to investigate the circulation of European smelted copper artifacts in Virginia during the 17th century.
- Dussubieux et al. reported in Archaeological and Anthropological Sciences on elemental and isotopic analysis of glass beads from northeastern Thailand to show network ramifications reaching as far as the Middle East and the South China Sea, as well as India and Sri Lanka.
- In Archaeometry, Gilg et al. used LA-ICP-MS and Raman at the Field Museum to study garnet beads housed at the Institute for the Study of Ancient Cultures at the University of Chicago. The beads are from Lower Nubia and spanned 4000 years, and the analysis revealed how the trade of such ornaments evolved in that region through time.
- Finally, in Latin American Antiquity, former Resident Grad Student David Reid (now Visiting Research Assistant Professor, UIC) used pXRF and LA-ICP-MS to investigate the circulation of obsidian in the Arequipa region of Peru during the Middle Horizon.
