Have you ever loaded 4x5 film before? Is every negative affected or only 2 of a box of 100?

Are those scratches?? How could they be black on the negative? How dry is your area, particularly where you load/unload film?

Might be edge emulsion....

Look like pressure marks to me. Did you have trouble getting the film sheets to seat in the holders, or go into the developing holders?

I'm pretty sure i did this too. I couldnt get negatives out of the holders and repeated efforts to lift edge with my nail to pull them out scratched them.

A toothpick or seam picker or whatever you can slide under negative to lift it enough to pull it out the holder did the trick for me.

Could it be a static discharge? You mentioned the film holders were 100% brand new which could have been holding a charge and when your finger touched the holder while pushing film in you became the ground. Other than that I'm with Donald, some type of damage while handling. Only one thing to do, try again.

Yes... as Donald noted the friction under pressure exposes the silver halide crystals like if emulsion was locally exposed to heavy light, then it develops, those marks in your samples were totally exposed.

Physical strains on film have to be avoided, such as pressure, buckling, creasing, friction, etc.
