RARE Fossil Ammonites Neoptychites & Vascoceras venezolanum – Turonian, Cretaceous – Morocco – Authentic Certified Fossils

Description

RARE Fossil Ammonite Pair – Neoptychites and Vascoceras venezolanum

Turonian Stage, Upper Cretaceous – Morocco

This exceptional fossil pairing features two beautifully preserved ammonite genera from the Turonian stage of the Upper Cretaceous: Neoptychites and the highly recognisable Vascoceras venezolanum. These specimens were collected from fossil-rich deposits in Morocco, a region known for its diverse Cretaceous marine fauna.

Geological & Scientific Context:

• Species: Neoptychites sp. & Vascoceras venezolanum
• Geological Period: Cretaceous
• Stage: Turonian (~93.9–89.8 million years ago)
• Provenance: Morocco
• Depositional Environment: Shallow epicontinental seas with calcareous marine sedimentation. These environments supported a rich ecosystem of cephalopods, bivalves, echinoids, and other marine invertebrates.

Taxonomic Classification:

For Neoptychites:

• Kingdom: Animalia
• Phylum: Mollusca
• Class: Cephalopoda
• Order: Ammonitida
• Superfamily: Acanthoceratoidea
• Family: Vascoceratidae
• Genus: Neoptychites

For Vascoceras venezolanum:

• Kingdom: Animalia
• Phylum: Mollusca
• Class: Cephalopoda
• Order: Ammonitida
• Superfamily: Acanthoceratoidea
• Family: Vascoceratidae
• Genus: Vascoceras
• Species: Vascoceras venezolanum
• First Described By: Renz, 1940

Morphology & Features:

• Vascoceras venezolanum typically exhibits a thick, evolute shell with prominent ribbing and nodose ornamentation, making it easily recognisable among Turonian ammonites.
• Neoptychites has a smoother, more compressed shell with variable ribbing, representing a transitional morphology within the Vascoceratidae family.
• Both ammonites illustrate evolutionary diversity and are often used for Turonian biostratigraphy.

Stratigraphy & Biozone (if applicable):

• These taxa are characteristic of the Middle to Late Turonian ammonite zones, often used for correlating marine sequences across North Africa, Europe, and South America.

Educational & Display Value:

This paired ammonite specimen is a rare find and serves as an excellent reference point for understanding Cretaceous ammonoid diversity. It is a standout addition for collectors, educators, and institutions with interests in paleobiogeography or cephalopod evolution.

Specimen Details:

• Scale Cube: 1cm – for full sizing, refer to the photograph
• Condition: Cleaned and professionally prepped
• Photo Accuracy: The photo displays the exact specimen you will receive
• Authenticity: Guaranteed 100% genuine, supplied with a Certificate of Authenticity
• Source: Ethically and responsibly collected from Cretaceous deposits in Morocco

Summary:

This RARE dual-specimen fossil featuring Neoptychites and Vascoceras venezolanum from the Turonian of Morocco is a unique example of Upper Cretaceous ammonite biodiversity. Ideal for fossil collectors, educational displays, and museum collections, it is a scientifically valuable and aesthetically striking piece.
