Notes on Ceratopsians at the National Museum of Natural History - Text

As part of my dissertation research and general research program focused on horned dinosaurs, I traveled to the Smithsonian (National Museum of Natural History, USNM, Washington, D.C., USA) in the spring of 2006 for a few days of research. Taxa discussed in these notes include specimens referred to Brachyceratops montanus , Triceratops spp., Pentaceratops sternbergii , Ceratops montanus , and Torosaurus utahensis .
