Once the bones had reached Braunschweig the preparators used a gentle method to free the bones from the plaster. Afterwards the surface of the bones was cleaned from any sedimentary rock that was still attached with help of an pneumatic engraving pen. After that, any bone fragments that had broken off could be glued back on and the glue joints were rubbed away. Missing parts were filled in with spattling compound.
