£36.00

This listing features a genuine fossil ammonite, identified as Calycoceras, from the Cenomanian Stage of the Late Cretaceous Period, discovered near Agadir, Morocco. A superb example from North Africa’s prolific fossil beds, this ammonite offers both visual appeal and geological significance. The specimen is presented exactly as shown in the photo, accompanied by a Certificate of Authenticity.

Geological and Paleontological Details:

  • Location: Agadir, Morocco
  • Period: Cretaceous
  • Stage: Cenomanian (~100.5 to 93.9 million years ago)
  • Depositional Environment: Marine chalk and marl environments within the Tarfaya Basin—rich in calcareous sediments and ammonite-bearing strata
  • Formation: Often from the Akrabou Formation or equivalent Cenomanian units of southwestern Morocco

Taxonomy:

  • Order: Ammonitida
  • Superfamily: Acanthoceratoidea
  • Family: Acanthoceratidae
  • Genus: Calycoceras

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.
