You guys crack me up. Gotta love you though!
It didn't take long for this thread to default to the board's main obsession -stone age boats.
To paraphrase your last few posts:
Could a shamanic drawing show a boat, thus proving that there were stone age boats?
My view?
I thought this thread was about showing that the artefacts are shamanic?

Although it would be great to also discover stone age boats!
So, moving on .....
I have already posted this in the Rock Art thread, but it also belongs in here:
The artefacts at our friend Alan Day's site are dated to the upper Palaeolithic.
If you haven't seen them already, click on the link to see examples of the carved rock artefacts at his site in Ohio which he considers to be pre-Clovis.

A bird facing forward on top of the head, often suggesting shaman headgear.
One or more birds or quasi-human faces emerging from the mouth, an apparent theme of regeneration, like the figure-emerging-egg-like and figure-from-the-belly imagery also shown below. Sometimes there is a succession of figures, each emerging from the one preceding it.
A bird or Bird Spirit emerging from the posterior in the manner of an egg, when the figure appears in full-length bird form.
The head of a bird or Bird Spirit emerging beneath the primary figure (when in full length form), as if from the belly.
The idea of a human merging with an animal is taken one step further here. The human seems to have been swallowed by the bird, and is being passed through its belly or its posterior.
Shamans have reported that their animal spirit helper can sometimes swallow them while they are in the altered state, and they consider this to be an initiation of sorts. As part of the initiation, the shaman will pass through the body of the animal or bird and then exit through its posterior or belly.
I have wondered if the story of Jonah and the whale is later version of that.
Eggs are also common shamanic motifs – the symbolism being obvious.
I think, as does Alan and several others, that he has a very good case for his artefacts being inspired by the shamanic.
