Description
This listing features a rare and scientifically important fossil ammonite of the species Juraphyllites diopsis from the Upper Pliensbachian Stage of the Early Jurassic, approximately 189 to 183 million years ago. This beautifully preserved specimen was found in Italy and comes from the esteemed Alice Purnell Collection, a notable source for well-documented and museum-quality fossil material.
Juraphyllites diopsis is a member of the Phylloceratina suborder, known for their elegant, involute shells with fine ribbing and suture patterns. These ammonites are often considered more primitive than later Jurassic and Cretaceous forms but display a delicate beauty in their morphology. As open-water swimmers, they played a key role in Early Jurassic marine ecosystems.
The preservation of this fossil captures its gently coiled form and delicate surface details, making it a highly desirable piece for both scientific reference and fossil collections.
Geological Context: The Upper Pliensbachian Stage (part of the Lower Jurassic system) represents a time when Europe was largely covered by shallow tropical seas. The Italian localities where Juraphyllites are found are known for producing well-preserved ammonites from limestone and marl beds that accumulated in warm, nutrient-rich marine environments. Fossils from this interval are important for biostratigraphy and evolutionary studies.
