RARE Hyphoplites curvatus Heteromorph Fossil Ammonite – Lower Cenomanian, Cretaceous – Sarthe, France – Alice Purnell Collection

RARE Hyphoplites curvatus Heteromorph Fossil Ammonite – Lower Cenomanian, Cretaceous – Sarthe, France – Alice Purnell Collection

Original price was: £60.00.Current price is: £54.00.

This listing features a rare and beautifully preserved Hyphoplites curvatus heteromorph ammonite fossil, dating to the Lower Cenomanian Stage of the Cretaceous Period, approximately 100 to 94 million years ago. This genuine specimen was discovered in the Sarthe region of France, a locality renowned for high-quality Cretaceous marine fossils. It is part of the respected Alice Purnell Collection, known for its well-curated and historically important fossil specimens.

Hyphoplites curvatus belongs to the group of heteromorph ammonites, which differ from typical planispiral ammonites by having uncoiled or irregularly coiled shells. These complex shell morphologies are believed to have affected their mobility and lifestyle, possibly indicating a more benthic or planktonic existence compared to their more streamlined relatives.

This specimen shows excellent shell preservation, with distinct curvature and detail. Its scientific importance and aesthetic uniqueness make it a prized addition for collectors or institutions.

Geological Context: The Lower Cenomanian marks the beginning of the Late Cretaceous and is known for significant marine transgressions that created widespread epicontinental seas. Fossil-bearing rocks from the Sarthe department provide rich assemblages of ammonites, belemnites, and other marine invertebrates. These strata are crucial for understanding Cretaceous paleoecology and biostratigraphy in Western Europe.

Key Details:

  • Species: Hyphoplites curvatus (Heteromorph Fossil Ammonite)
  • Fossil Type: Extinct marine cephalopod
  • Age: Lower Cenomanian, Cretaceous (~100–94 million years ago)

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.
