Doll? It looks like a salt shaker, or maybe a decorative bottle stopper depending upon scale.

I wonder why they believe it is a doll rather than a religious idol of some kind?

[Persevero]

I know, with all similar finds, I wonder, how do they know it was a doll?

Could have been sculpture, idol, even a porn item, bottle top as you mentioned, memorial of a dead child/person, who knows?
