What is this? A birthmark?

I just got two new female leos. They were both bought from a petstore two years ago and have shared an enclosure since then. After the guy dropped them off today I was looking over them and I noticed they both have this weird dark brown mark on them. Reminds me of a birthmark. What is it? I have included pictures.

Birthmarks, I have quite a few animals with Random birthmarks like that.

I have a male that has something exactly like that on the exact same leg. It never got bigger or smaller so I just ignored it.

Okay I have been told it is a paradox spot. Still i think it is weird that they both have it.
