A cave wall with embedded bone and mysterious sign are shown.
An extreme close up view of a well lit cave wall with a bone embedded in it. The cave wall looks like dried mud and rocks. It is a light gray and light tan color. There is a small orange washer with a pin nailed into the wall. The pin is in the center of the image. A white square paper sign in a clear plastic sleeve is to the left and below the pin. The sign tilts down to the right. The text is printed in a black san serif font. It says,"Unidentified / Animal" on it. The bone in the wall is in the upper middle center of the frame. The bone is a pair of horizontal and parallel bones that tilt slightly down toward the bottom left. The bottom bone has more of an arched curve on its left end.
