A Thorn in the Side: Space-Efficient Storage of Large Ribs

In 2022, Fort Hays State University’s Sternberg Museum of Natural History (FHSM) began a project to address the long-term preservation of a Late Miocene mammal collection. Many of the fossils from the collection were poorly consolidated, uncurated, and improperly stored, leaving them unstable and prone to significant degradation. As part of our housing overhaul, we worked to develop new methods of housing rib bones, which are often too large to fit in traditional archival boxes. Two versions of rib mounts were developed using wedges of Ethafoam (closed-cell polyethylene foam). This housing method provides a cost effective way to safely store these fragile fossils.
