CA glue is the most advisable glue to use in stabilization and preparation of bones. One can use it to repair broken bones whether in the field or in the lab. In addition, it can be used with an accelerator to avoid wastage or saturation of porous bones.

How do you stabilize a fossil?

Fossils that are not porous but which should be stabilized can be fitted with a superficial adhesive. Finally, an unstable matrix sometimes can be fixed at the bottom, e.g. by using an epoxy glue. The shell of this gastropode in clay has been superficially fixated with a reversible glue solution.
