The best place would probably be the first place you found. The archeologist wouldn’t have any clue to the exact position the person was in and over digging could ruin the find
The person making the illustration though knew what they were doing.
Approximate placement I guess. Stonework would survive, wooden structures would collapse, human and animal remains would naturally form a curved cavity that’s relatively strong.

I do wonder how they knew it was a person shaped cavity vs a plain old hole in the ground.
