I have an ammonite(?) that I received circa 1990 from a missionary who said that it was "brought down from the mountains by monks" in Papua New Guinea. Apparently, there is relatively little known about the palaeontology of the area. There are similar ammonites showing up in native tribal art pendants (see article in "Deposits Magazine" HERE The article indicates that it is not known whether these ammonites that are showing up are recently imported or of local origin. I suppose mine could have been imported, but given the date of acquisition and what I was told, I am inclined to think it was collected in situ in Papua New Guinea, but I can't be certain. The geologic map I found did not distinguish between periods in the Mesozoic, so I don't know if it is Cretaceous or Jurassic, etc. I did find 2 papers (Both available as .pdf online): Tatsuro, M & S.K. Skwarko. 1991. Ammonites of the Cretaceous Ieru Formation, western Papua New Guinea. J. Australian Geology & Geophysics 12(3): 245-262 Tatsuro, M & S.K. Skwarko. 1993. Cretaceous ammonites from south-central Papua New Guinea. J. Australian Geology & Geophysics 14(4): 411 - 433. The closest resemblance of the taxa in those papers was Subthurmannia (Fauriella) boissieri. In doing my own searching, I thought Macrocephalites bifurcatus (middle Jurassic) looked like a good match and has been collected in Papua (see link to museum specimen HERE). The preservation of that specimen appears to match mine, too. Here are some pics of my specimen. Any help from the ammonite enthusiasts would be greatly appreciated! @Ludwigia
