This is an absolutely beautiful block of ammonites. These ammonites are Peresphinctes from the Jurassic Period of Russia. There are FOUR gorgeous ammonites clustered together on the large block of limestone, the largest two being over two inches across. This type of ammonite has a distinct ribbing pattern - this feature is easily seen on these examples. All of the ammonites are extremely robust and exhibit very fine detail - even the tiny inner whorls of the ammonites are wonderfully displayed! The ammonites have brilliant natural coloration - they even retain the highly iridescent, mother-of-pearl shell (the rainbow of colors are much more vibrant in person than what the pictures show). The ammonites are beautifully showcased on the colorful block of concretionary matrix. This is a fabulous display plate of iridescent ammonites from Russia.
