It is rare for any project in the natural sciences to be completed without experiencing setbacks. When these unexpected problems present themselves, it is up to us as scientists to deal with them and continue our research!

 The repository has recently received Quaternary subfossil specimens that have been undergoing careful treatment for research and exhibition. The specimens were kept moist until arrival, where they were then placed in drying chamber micro-environments. These chambers are excellent for retaining moisture and keep conditions such as temperature and humidity from experiencing high degrees of fluctuation. Unfortunately, this method has worked a little too well...

 By keeping the specimens within the constructed drying chambers, moisture and temperature have remained stagnant for extended periods of time. Combined with the lack of airflow, which is permitted by the overhead polyethylene sheets, and the result is the growth and propagation of mold. The morphology of the mold has been moderately variable: from full blooming forms to much more subtle, thinner layers. The presence of mold on these fossil specimens poses a serious health hazard to repository staff. Additionally, the growth and propagation of mold on the specimens poses a high risk to damaging both the physical and chemical characteristics of the bone surfaces on which it grows. Mold also causes the specimens to take on a very pungent mildew aroma, making them unideal for exhibition. For these reasons, mold MUST be quickly dealt with.
