Here’s a few - all at the same link. Some inside the top left the poly, one just above it, and the croc (& letter X) half in and half outside of poly (top left).
A mummy (Egyptian that is!)
A crocodile head (with the letter X)
Multiple letters (ancient writing? :rofl
EDIT: I came across two more items in this same map link. A very large face above the poly, and multiple faces, a “sci-fi” boney beast and a small strange animal. Giving my eyes (and brain) a break before I start seeing things in the trees when I step outside.
This photo is above the large face.
