I haven't seen a lot of details about the method online, but from what I understood it is quite coarse, and for anything more specific one would have to do DNA analysis. ....
Apart from knowing which animal has been processed, an investigation of the origin would be extremely interesting. DNA research could certainly provide information, but a common method of origin determination is the study of stable isotopes (SIRA). At least in the (European) food industry and its supervisory authorities, this determines the origin of meat products. The concluding remarks of a paper from 2016 summarize:

Stable Isotope Ratio Analysis for Assessing the Authenticity of Food of Animal Origin
Federica Camin, Luana Bontempo, Matteo Perini, and Edi Piasentier
....
Geographical, climatic, pedological, geological, botanical, and agricultural factors affect the stable isotope ratios of bioelements in nature, and isotopic variations are ultimately incorporated into animal tissue throughout eating, drinking, breathing, and exchange with the environment, being memorized in the resulting foods. As a consequence, the stable isotope ratios analysis of H, C, N, O, and S has shown high potential for determining geographical origin, animal diet, and the production system ( organic / conventional ) for pork, beef, poultry, milk, butter, cheese, fish, and shellfish.

I do not know if such methods are used in codicology.
