Well the cuts----see it every day !
The epidermis loss is from it not drying and staying wet to long. Ever pay attention to how long your skins lay in the salt ? Plus most places I've been, its wet used salt. I have a client that said his lion was in the salt 14 days and they never did pick it up and dry it while he was there. With 10 other animal capes on top of it, it will be a problem.
Skins soaked in bactericides only delay the action of the bacteria. Good dry salt does the same thing.
Another cause is the salted skins being dried in the direct sun or they get to hot sitting waiting to be exported. ( that's why its so important to get them shipped out as quick as possible) Salt in some locations is to high in Alkaline. Problem with these last couple deals is that Whom ever tans them must over work the skin to get it to rehydrate for tanning. Thus slipping and epidermis loss etc. Some also fold the skins up while still wet. Its more complex than most would believe.
Remember----salt doesn't penetrate into a skin to magically preserve it. It pulls all the moisture out a skin so as bacteria has no place to live. Wet bad--- dry good. Wet salt isn't good at drying skins. Failure at this drying process causes problems.
In the perfect environment a skin should be heavily salted in new salt for 24 hours than re-salted in new salt and left for 2 to 4 days more, than picked up and hung on drying rack with good air circulation until barely foldable. With no other skins piled on top of it.
Most problems can be narrowed down to skin care in one way or another.
In general wet tans instead of dry tans will produce a better skin for mounting as far as epidermis loss and damaged parts are concerned.
Some are more delicate than others like Hyena, Impala , Nyala, warthog to name a few
This baboon from Limpopo is the best I've seen in a while. It almost has 2 full eyelids. But ears only half way turned.
Salting skins is one of the most misunderstood process in taxidermy.
Great post Buck Wild !
