Does this capstone over the entrance to the barrow contain an animal's head?
Some claim to have seen the carving of a deer, others a water buffalo. Is this natural or not?
If this stone is genuine, and replaced in its original position after restoration, it would have been visible even after the barrow was sealed up.

Checked that out after being posted by terence meaden on the avebury forum. stands out like a sore thumb once pointed out. Looks like a cow to me.
