FOSSIL AMMONITES

(updated 12/5/08)

These specimens are from Morocco, Madagascar, and Russia. Ammonites lived in the sea, much like our present-day nautilus does, and are related to present-day octopus and squid.

__These are ammonites from Morocco (Goniatites, Devonian age). They have been polished all around and shaped, but they contain the actual fossil. (#G04-787, $46). We always keep a large stock of these popular fossils, priced from $8-$46, with most less than $20.

__Ammonite, Mahanjanga Province, Madagascar (Jurassic age, #G07-1249, $24 for the pair). It has been cut in half and polished on both sides, including the back. We have several flats of these, in a variety of sizes and colors, and prices range from $6 - $80, with most under $20. A couple more examples are shown below.

__ A darker colored ammonite, which is not polished on the back (#G07-1246, $20 per pair).

__This is a different ammonite specimen from Madagascar, and is a different species from the one above (Cleoniceras, Cretaceous age). (#G06-383, $24). These are polished on both sides and many of them, like this one, are opalescent. Prices on these range from $6 for small sizes to $110 for larger ones (4-5 inch diameter).

__This is a "pyritized" ammonite (G08-077, $48), in which the shell material has been replaced by pyrite ("fool's gold"). It is middle-Jurassic age, and is from Mickhailov, Russia. It's been cut down the middle and polished on the inside; the outside still has some irridescent shell material (see photo below). We try and keep a good stock of these, and prices range from $26 - $58.
