Pattern of follicle marks.
If during the preparation of the parchment, some of the grain layer was preserved, it is possible to determine the animal species based on the pattern of the follicle marks. The degradation or gelatinisation of the parchment may often be related to the follicles marks in the grain layer. As the result of the parchment’s degradation in the region of the holes is significantly more yellow and thereafter, the pattern of the follicle marks is clearly discernible on the surface of the skin.
