One recurrent topic when managing zoological collections is that many specimens has not information of date when it was collected, dead or prepared. This information (besides the collecting place or author) is very relevant from a scientific perspective. There are many analytical methods to date old material that have been developed in the field of palaeontology and archaeology (i.e C14; U-To; K-Ar, termoluminescense, ranging from 200-500.000 years).
However, I wonder if any objective and faithful method has been developed for dating 10-200 years-old specimen made in organic material like skin, hair-feathers or bones. There are some indirect methods for taxidermies like the presence of As, eyes design, authorship etc., but I find them very inaccurate and only applied for local collections.
Any idea or paper?
Thanks in advance.

whether it is the human being or the animal, all have the same chemical composition of the bones ???????????? then there are several analytical methods for example (nanomaterials polymer, resins, thermoplastic membranes). All that is termosensible and termoplastic ????????????? Tank you
U-Th-He radiogenic isotopes are used to date apatite in geological systems and resolution can be more or less your desired range. It is very expensive and I do not know if is OK for skeletons but... just an idea.
