Fossil Bivalve Neithea casteeli Turonian Cretaceous Spain Genuine Collectors Specimen

Description

Genuine Fossil Bivalve – Neithea casteeli

This listing features a beautifully preserved fossil bivalve, Neithea casteeli, originating from the Turonian stage of the Late Cretaceous, discovered in Spain. This fossil is a fine representation of the diverse and abundant molluscan life that flourished in the warm epicontinental seas of the Cretaceous period. A carefully chosen and photographed piece, the specimen you see is the exact one you will receive. Each fossil includes a Certificate of Authenticity, guaranteeing its provenance and genuine natural origin.

Geological Context

The fossil was unearthed in Turonian-age deposits, dating to approximately 93–89 million years ago, during the Late Cretaceous. The Turonian represents a time of high global sea levels when shallow marine environments extended across much of Europe, including the Iberian Peninsula. These seas were rich ecosystems that supported a wide variety of invertebrates, such as ammonites, echinoids, and bivalves like Neithea.

The sediments that preserved Neithea casteeli consist of marine limestones and marls, deposited in calm, shallow-water settings. Such environments were ideal for benthic organisms, as fine-grained sediments captured and fossilised delicate shells, leaving a detailed record of their morphology for millions of years.

Taxonomy and Classification

• Kingdom: Animalia
• Phylum: Mollusca
• Class: Bivalvia
• Order: Pectinida
• Superfamily: Pectinoidea
• Family: Pectinidae
• Genus: Neithea
• Species: Neithea casteeli

Neithea species are scallop-like bivalves well-known in the Cretaceous fossil record. Their distinctive shells and wide geographical distribution make them an important genus for palaeontological study and fossil collecting.

Morphological Features

Neithea casteeli displays several notable characteristics:

• Unequal valves: One convex and one flatter, typical of the genus Neithea.
• Prominent radial ribs: Extending across the shell surface, providing structural strength and visual distinction.
• Curved growth lines: Evidence of incremental shell development through the bivalve’s lifespan.
• Pectinoid form: Closely resembling scallops, with features adapted for stability on soft seabeds.

These features made Neithea casteeli a successful inhabitant of the Cretaceous marine environment, capable of living in relatively shallow, nutrient-rich waters.

Scientific and Collector Importance

This fossil is valued for both its scientific significance and aesthetic appeal:

• It contributes to understanding the biodiversity of Turonian seas, providing key data for palaeontologists studying marine faunas of the Late Cretaceous.
• As a well-preserved specimen, it demonstrates the shell morphology that defines Neithea, aiding comparative taxonomy.
• Its symmetry and ribbing create a naturally attractive display fossil, ideal for collectors and enthusiasts.

Because Neithea species were widespread and well-dated, they are also significant for biostratigraphy, helping to correlate Turonian deposits across Europe and beyond.

Provenance and Authenticity

This fossil bivalve was recovered from Cretaceous Turonian deposits in Spain and is guaranteed to be 100% authentic. Every specimen is supplied with a Certificate of Authenticity. No restoration or alteration has been carried out, ensuring you receive a genuine piece of natural history.
