You mention an "extinct bird from Samoa." What part of the bird are we discussing?

The claw-like pendants, I suspect, are tusks from some member of the pig family. The wart hog, for instance, lives in Somalia (NE Africa). And the roots of their tusks look very much like The pendants in your necklace.

I have to wonder whether "Samoa" and "Somalia" have become confused (?).

I will harvest a photo from my Ivory Seminar, and post it here.
