Here is an attractive ammonite specimen from the Jurassic of Russia. There are two examples of Cosmoceras sp. on the block. This type of ammonite has fine ribbing and a very sharp keel. Both ammonites are very 3-dimensional and exhibit great detail. The inner whorls of the ammonites are clearly defined and the nacreous shell is exquisitely preserved. The completely natural, iridescent coloration of the fossils is wonderful (much better in person than what the picture shows). A dusting of sparkling pyrite crystals adds a distinctive touch. The ammonites are well positioned on the plate of concretionary matrix. This is a very pretty multiple ammonite specimen from Russia.
