Sculpted Stone

This is a fabulous multiple ammonite fossil. It is a cluster of Hoploscaphites nicolleti from the Cretaceous of South Dakota. There are FIVE ammonites in this concretion, two of which are extremely displayable (a third colorful ammonite is seen in the last photo, and is preserved on the back side of the plate.)This type of ammonite has numerous ribs that are coarse in the beginning and becoming very fine near the living chamber. The keel is flat and narrow with a row of prominent nodes on both sides. Both of these ammonites are very 3-dimensionally preserved and exhibit fine detail, and BOTH cephalopods have the full living chambers present, which is quite unusual. The iridescent ammolite nacre displays a wide variety of colors, mostly reds and greens. The striking ammonites display beautifully in the large, natural block of concretionary matrix - again, there are two main display ammonites, but there are actually FIVE ammonites preserved in the concretion! This is an extremely colorful and highly collectible multiple example of Hoploscaphites from the Badlands of South Dakota.
