Translation:
"I found the turtle almost on top of a hill, it has some stones that make a line from east to west, its head faces south and what appears to be its tail faces north
It has some holes in the side of the shell and one hole with something that looks like a circle on top of the shell, I will also send photos of that"
Looks to me like fossil coral porites/microatoll. Possibly someone came along and stylized them into turtle shapes.
