The many and various artifacts in bone preserved in the museum come from specialised workshops. Stag horn and cattle metatarsals were the favourite materials of the Gallo-Romans.

Thanks to the three hundred cattle metatarsals on the site, it is possible to recreate the various stages in the making of hinges.

First of all, the bone must be sawn and the diaphysis or main body of the bone using a hammer separated from the epiphyses, or ends of the bone. The diaphysis is then subdivided into two or three segments. With the help of scissors the bone is then trimmed and then turned on a lathe. Lateral holes are then drilled through it and any additional decoration added before it finally emerges as part of a hinge. One, dating from the late Tène culture is decorated with a fish bone pattern and perfectly rectangular hole.
