RARE: 9" Perisphinctes caroli Fossil Ammonite, Bathonian Jurassic, Malmesbury Wiltshire UK – Authentic Specimen with COA
£ 360.00
A stunning and rare 9" Perisphinctes caroli fossil ammonite, collected from the
Bathonian Stage of the Middle Jurassic, found near Malmesbury, Wiltshire, United Kingdom. This exceptionally preserved specimen represents a classic ammonite genus from one of the UK’s renowned fossil-bearing regions.Taxonomic Classification:
• Genus: Perisphinctes
• Species: caroli
• Order: Ammonitida
• Superfamily: Perisphinctoidea
• Family: Perisphinctidae
• Originally described by d'Orbigny (1846), the genus is a major ammonite group found globally in Middle to Upper Jurassic rocks.Geological Context:
• Stage: Bathonian (Middle Jurassic)
• Age: Approximately 168 to 166 million years old
• Formation: Forest Marble or surrounding Bathonian limestones and marls
• Location: Malmesbury, Wiltshire, UK
• Depositional Environment: Warm, shallow marine shelf dominated by calcareous sediments and oolitic facies. The Bathonian seas supported a rich diversity of ammonites, bivalves, and marine reptiles.
• Biozone: Often associated with the Procerites and Perisphinctes zones in Bathonian ammonite stratigraphyMorphological Features:
• Strongly ribbed, evolute shell with all whorls visible
• Ribs are typically bifurcating or trifurcating, sweeping from the umbilicus across the flanks
• Broad, rounded venter and moderately inflated whorls
• May show growth lines and intricate suture patterns in well-preserved specimensScientific Significance:
• Perisphinctes caroli is a valuable index fossil for dating Bathonian strata
• Its distinct morphology helps in regional correlation across Europe’s Jurassic formations
• The species contributes to understanding ammonite evolution during the Middle Jurassic, especially within the Perisphinctid lineageThis fossil is shown with a 1cm scale rule cube, and the actual specimen pictured is the one you will receive. It was carefully selected for its completeness and visual appeal.Authenticity Guaranteed: This is a 100% genuine fossil ammonite, provided with a Certificate of Authenticity. Ideal for fossil collectors, natural history enthusiasts, or as an outstanding display specimen.Please see all photographs for full details and accurate sizing. This is a rare opportunity to own a top-quality Bathonian ammonite from Wiltshire, rich in geological history and scientific value.
