Quenstedticeras sp.
Vendor: Fossil Soup
SKU Number: SQ1255770
Quenstedticeras is an Upper Jurassic ammonite that occurs in many parts of Europe. This specimen was collected from the Mikhailov Quarry in Ryazan, Russia. The outer shells have a pearl-like iridescence with ornamentation of forward sweeping ribs that are inflated and 3D. These ammonites are often mounted on concretions with pyrite, as is the case here, for display purposes. This piece is especially unusual in that it has both the outer shell of the ammonites as well as the polished cutaway of the outer chambers.
The ammonite, pyrite and septarian nodule that it sits on, are composited (comprised of disparate or separate parts or elements not found together) to create an attractive display piece.
These ammonites were preserved in anoxic conditions where mineralization took place and the original shell was replaced with pyrite. Cross sections of these ammonites beautifully showcase the growth chambers and the crystals of pyrite that line the walls. This is truly a beautiful display piece.
Full dimensions are listed below (Dimensions are for the larger of the 2 ammonites)

Additional Information
The classic region where these rocks outcrop is the Volga region of Russia, including Nigniy-Novgorod, Ulyanovsk and Saratov. In the Ulyanovsk region, the Volga river flow cleaves the Middle Jurassic and Lower Cretaceous sediments at the length of more than 100 kilometers, which provide many outcrops with an abundance of fossil material, including sea reptiles, sharks, fish, cephalopods and gastropods. The fossil hunting on the Volga river banks starts in early spring when ice on the river has not yet melted.
