Rare Stantonoceras pseudocostatum Fossil Ammonite Campanian Cretaceous Russia
£ 48.00
RARE STANTONOCERAS PSEUDOCOSTATUM FOSSIL AMMONITE FROM RUSSIAPresented here is a rare Stantonoceras pseudocostatum fossil ammonite, dating
from the Campanian Stage of the Late Cretaceous, originating in Russia. This authentic fossil has been carefully chosen for its quality, character, and scientific value. Supplied with a Certificate of Authenticity, it represents a fascinating specimen from a period when ammonites flourished in the warm seas of the Cretaceous. The photographs show the exact fossil you will receive, with a 1 cm scale cube included for accurate sizing. GEOLOGICAL AGE AND PROVENANCEThe Campanian Stage (83.6–72.1 million years ago) is a critical interval of the Late Cretaceous, known for widespread marine transgressions and rich ammonite faunas. The fossil-bearing strata of Russia have produced a number of rare ammonite taxa, and Stantonoceras pseudocostatum stands out as a significant and scientifically valuable species. This fossil provides insight into the paleobiogeography of ammonites across the northern hemisphere during the Late Cretaceous seas. SCIENTIFIC CLASSIFICATION
• Kingdom: Animalia
• Phylum: Mollusca
• Class: Cephalopoda
• Order: Ammonitida
• Superfamily: Desmoceratoidea
• Family: Kossmaticeratidae
• Genus: Stantonoceras
• Species: Stantonoceras pseudocostatumThis taxonomic group belongs to the Kossmaticeratidae, a family of ammonites with distinctive ornamentation and significant value for biostratigraphy. The genus Stantonoceras is notable for its rarity in the fossil record and the high level of detail preserved in its shell morphology. MORPHOLOGICAL FEATURESStantonoceras pseudocostatum is recognized by its moderately involute shell, with strong ribbing that creates a striking sculptural effect across the flanks. The ribs are often broad and may bifurcate or branch toward the venter. The whorls show a rounded section, giving the fossil a robust and well-defined appearance. These features not only make it visually distinctive but also play an important role in its identification within the Campanian ammonite faunas. PALEOENVIRONMENT AND SIGNIFICANCEDuring the Campanian, the Russian region where this specimen was found was submerged beneath shallow marine environments, connected to broader epicontinental seas. These seas provided abundant food resources such as plankton and small crustaceans, sustaining diverse populations of ammonites. Fossils of Stantonoceras pseudocostatum are considered rare and highly valuable in paleontological research, serving as important index fossils for correlating Campanian deposits across Eurasia. COLLECTOR AND DISPLAY VALUEThis specimen of Stantonoceras pseudocostatum is highly sought after due to its rarity and well-preserved shell features. Its bold ribbing and distinct morphology make it an impressive display piece for collectors of rare ammonites. With its scientific importance and attractive natural form, it is suitable for advanced fossil collections, museum displays, or as a unique centerpiece for enthusiasts of Cretaceous paleontology. KEY FEATURES
• Rare ammonite fossil from the Campanian Stage of the Late Cretaceous.
• Species: Stantonoceras pseudocostatum, distinctive for its strong ribbing.
• Provenance: Russia, an important Cretaceous fossil region.
