Dark lines in displacement map bake

I’m having here a little problem with baking a displacement map for a dinosaur I’m working on. If you were to look onto the texture you can see a bunch of dark lines in a pattern, which I don’t want. I have no idea what’s causing it, I know it wasn’t happening when I used older versions before on other projects in the past. Any Ideas what I could do to solve it.

here’s the link to the blend file if you want to take a look at it.
