FOSSIL AMMONITES

(updated 1/18/2010)

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-$80, with most less than $20.

__Ammonite, Mahanjanga Province, Madagascar (Jurassic age, #G07-1243, $28 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 - $40, with most under $20. A couple more examples are shown below.

__ A darker colored ammonite (#G07-1228, $18 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__This is a "pyritized" ammonite (G09-343, $38), in which the shell material has been replaced by pyrite ("fool's gold").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, and still has some shell material on both sides. We try and keep a good stock of these, and prices range from $28 - $50.

__Another example of the pyritized ammonites (Cosmosceras). This one has not been polished, but contains pyrite on the inside. (#G08-088, $38)
