£18.00

This Rare Olcostephanus sulcosus Fossil Ammonite is an outstanding specimen from the Hauterivian stage of the Cretaceous period, discovered in Russia. The fossil is a 100% genuine specimen, accompanied by a Certificate of Authenticity. The Olcostephanus sulcosus ammonite is a highly sought-after species known for its distinctive spiral shape, fine ribbing, and well-preserved features, making it an excellent addition to any fossil collection.

Geology and Fossil Type

  • Geological Stage: Hauterivian, Cretaceous
  • Depositional Environment: Marine (During the Hauterivian period, the warm, shallow seas provided the perfect environment for ammonites like Olcostephanus sulcosus to thrive, eventually becoming fossilized in regions like Russia.)
  • Family: Stephanoceratidae (A family of ammonites known for their smooth, coiled shells and characteristic ribbing)
  • Superfamily: Ammonoidea
  • Order: Ammonitida (Ammonites belong to the Cephalopoda class, related to modern squid and octopus)

Morphology Features

The Olcostephanus sulcosus ammonite features a smooth, tightly coiled spiral shell with distinct ribbing running along the surface. The shell is characterized by its elegant spiral form and fine ribbing that gives the fossil a highly textured appearance. The suture lines are clearly visible, providing insight into the internal structure of the ammonite, which helped it navigate the ancient seas. The overall smooth curvature and subtle texture make it an attractive and well-preserved specimen.

Notable Features

This ammonite is especially notable for its exceptional preservation and distinct ribbing. The Olcostephanus sulcosus species is relatively rare, making this fossil a prized find for collectors. Its smooth spiral shape, distinct ribbing, and well-preserved internal suture lines make it an ideal specimen for studying the marine adaptations of ammonites from the Hauterivian period. The fine preservation of the fossil enhances its scientific and aesthetic value.

Cretaceous Information

The Cretaceous Period (145–66 million years ago) was the final era of the Mesozoic, marked by the dominance of dinosaurs and the rise of flowering plants. It had a warm, greenhouse climate, with high sea levels that created vast shallow inland seas. Marine life flourished, including mosasaurs, ammonites, and rudist reefs, while the land was ruled by iconic dinosaurs like Tyrannosaurus rex, Triceratops, and Spinosaurus. Mammals and birds diversified, and insects thrived. The period ended with the mass extinction event, likely caused by an asteroid impact, wiping out the dinosaurs and paving the way for the rise of mammals in the Cenozoic.
