Since I originally started this thread, I found finally found one mention in one source from George Frederick Kunz in his book Ivory and the Elephant in Art, in Archaeology, and in Science, 1916, p348:
“The molar of an elephant has been found in the island of Luzon, Philippines. This was probably brought thither from India. On the island of Mindanao a tooth of Stegodon trigonocephalus mindanaoensis was discovered. This genus stands between the mastodon and the modern elephant, although more nearly resembling the latter. This is the only instance on record of the finding of such remains in the Philippine Islands. The tooth was found in the north- western part of the island, and is at present in the Ethno- logical Museum at Dresden (No. 2679). The discovery was made by Semper, who described it as "a tooth of the war god Tagbusu of the Manobos, only to be worn by a Bagani (a priest or a prince); it was used as a talisman."
The tooth is bound with varicolored strings, so attached that it could be worn suspended.”
If you folks find any other information, please post or let me know.
I have attached close ups of the stegodon fossil molar pommel.
Also here is a link of the discussion of this type of material over at the kerns forum:
