In 1985, when Princeton University ceased it paleontology program, the Yale Peabody Museum acquired the specimens of the Princeton Collection. We received grant funding from the National Science Foundation to conserve this part of the Peabody paleontology collection. All of the specimens will be re-housed in foam-lined, inert specimen trays, to support and protect them for future research. Like most of our collections these specimens, although not on public display, are extensively studied by scientists from all over the world. Conservation projects like this one are vital to the Museum because they help us to maintain our important fossils.
