Scientific Significance: Euhoploceras mayeri is a less commonly encountered ammonite species from the Middle Bajocian, making it a rare and scientifically relevant find. As a member of the Graphoceratidae family, it helps define key biozones used in Jurassic marine stratigraphy throughout central Europe. Fossils like this one aid in correlating marine sedimentary layers across Germany, France, and the UK.
Formally described by 19th-century paleontologists during the golden era of Jurassic ammonite taxonomy, E. mayeri remains an important index fossil in Bajocian studies.
Ideal for:
- European Jurassic fossil collections
- Stratigraphic or biostratigraphic study
- Museum-quality display or educational collections
