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 Protective, secure packaging   Please feel free to contact us with any questions.
