Need help identifying!

Hey everyone, still exploring the rock were I found those two square Holes and the two square etchings. I started digging at the bottom of the rock and I've ran into a few things I've never seen or heard of.
Please look through these pics and see if you can help me out with this one.

What you are probably seeing is just a seam in the sedimentary rock face.

notice how the lines go around corners but stay the same, indicating they are natural.
