Fossil Molar Talisman Research Needed

[Jean]

I attach pictures of fossil teeth which I got in Sangiran (near Solo) some 15 years ago, they are too small for making a hilt and may not come from a mammoth at all. I think that this site was extensively excavated and is highly controlled so I doubt that fossil teeth are still available from this location and used for making artefacts, but it was probably the case in the past.
I attach a picture of a Jogja kris in my collection with the hilt & waranga made from elephant molar (from Sumatra?), I bought it 5 years ago and the materials is still strong, as I said I think that it may not be that old so the organic binder in the tooth is still present and avoids it to be too brittle.
Best regards
Jean
