Geological & Scientific Information:

  • Fossil Type: Ammonite (complete or near-complete shell)
  • Species: Euhoploceras modestus
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Graphoceratidae
  • Geological Stage: Lower Bajocian (approx. 170.3 – 168.3 million years ago)
  • Period: Jurassic
  • Locality: Bretteville, Calvados, Normandy, France
  • Depositional Environment: Shallow epicontinental marine basin, likely soft mud or carbonate-rich seafloor sediments

 

Morphology & Notable Features:

  • Strongly ribbed shell with fine and dense ornamentation
  • Whorl section typically compressed with sharp ribbing extending over the venter
  • Ribbing bifurcates from the umbilical shoulder and crosses the flanks evenly
  • Well-defined suture patterns may be visible on close inspection
  • Characteristic of the genus Euhoploceras, which is noted for its sharp ribbing and moderate involution

 

Scientific Significance: Euhoploceras modestus is a rare ammonite species valuable in Lower Bajocian biostratigraphy, helping paleontologists to date and correlate marine sediments across Europe. These ammonites are part of the Graphoceratidae family, which represents a major evolutionary branch of early Middle Jurassic ammonites.

The genus Euhoploceras and its species were originally described in the 19th century by prominent European paleontologists, with E. modestus known primarily from French and some German localities.

 

Ideal for:

  • Collectors of European Jurassic ammonites
  • Educational institutions and geological studies
  • High-quality fossil display

 

Included With Purchase:

  • The exact Euhoploceras modestus fossil shown
  • Certificate of Authenticity

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
