A choice of absolutely tiny cut & polished ammonites from Madagascar. They have various shades of brown or golden calcite filling their chambers. Each specimen is discreetly glued onto a base so that it stands nicely. I think that these are the centres of larger fossils which have been worked down to this size; the middle one has a small saw cut that shows from the back and top, so is priced lower. These tiny fossil will work I think in any of the miniature scales.
Ammonites are extinct relatives of modern day nautiloids and squid. The largest known ammonite in the world would have been 8 1/2 feet (2.59 metres) across if it were complete.
