Rare Fossil Ammonite Parawedekindia arduennensis Jurassic Oxfordian Ardennes France | Authentic Fossil

Description

This listing features a rare and scientifically notable fossil of Parawedekindia arduennensis, an uncommon ammonite species from the Lower Oxfordian stage of the Jurassic period. The specimen was recovered from the well-known fossil-rich marine deposits of the Ardennes region, France, an area renowned for its Jurassic ammonite diversity and stratigraphic significance.

Geological Context:

• Fossil Type: Ammonite (Extinct marine mollusc, related to squid and cuttlefish)
• Species: Parawedekindia arduennensis (Dumortier, 1876)
• Order: Ammonitida
• Superfamily: Perisphinctoidea
• Family: Aspidoceratidae
• Geological Stage: Lower Oxfordian (c. 163.5 to 161.5 million years ago)
• Formation: Oxfordian marine limestones and marls
• Depositional Environment: Shallow epicontinental marine shelf with carbonate sedimentation

Parawedekindia is a genus appreciated for its finely ornamented shells and distinctive ribbing. Specimens like P. arduennensis are rare in the fossil trade and valued by collectors for their paleontological relevance and aesthetic qualities.

Morphology & Notable Features:

• Evolute to moderately involute shell structure
• Densely ribbed flanks, often with bifurcating ribs
• Rounded venter, sometimes with subtle tubercles or nodes
• Strong and clear suture patterns indicative of the Aspidoceratidae family
• Notable as a zonal marker in Lower Oxfordian stratigraphy

Biozone Association: Parawedekindia arduennensis is typically associated with the Cordatum Zone of the Lower Oxfordian and aids in refining the biostratigraphic framework of Early Oxfordian sequences across Western Europe.
