RARE Lower Turonian Ammonite Fossil Cretaceous Gombe Nigeria Authentic Certified Collectible

Description

Presented here is a rare Lower Turonian ammonite fossil from the Cretaceous deposits of Gombe, Nigeria. This remarkable specimen represents a window into the ancient marine ecosystems of West Africa during the Late Cretaceous, approximately 93.9 to 89.8 million years ago. Ammonites are extinct marine molluscs closely related to modern squid and octopus, with their coiled shells and intricate suture patterns making them some of the most distinctive and valuable fossils for collectors.

This particular ammonite was carefully selected for its preservation and scientific interest. It comes with a Certificate of Authenticity, confirming that it is a genuine specimen. The accompanying photos display the exact fossil you will receive, with a 1 cm scale cube provided for accurate sizing.

Geological Age and Stratigraphy

The Lower Turonian stage marks the earliest interval of the Turonian, a subdivision of the Late Cretaceous epoch. During this time, Earth experienced some of the highest sea levels in geological history, creating shallow inland seas that supported thriving marine life. The deposits of Gombe in Nigeria are part of this global record, offering fossil evidence that helps paleontologists reconstruct the biodiversity and ecological conditions of the period.

Ammonites from this stage are used as index fossils, allowing scientists to date and correlate rock layers across different regions. Their relatively rapid evolutionary changes make them excellent markers for understanding the timing of geological events and faunal turnovers during the Cretaceous.

Morphological Features

Although ammonite morphology varies widely between species, Turonian ammonites are typically characterised by planispiral shells with ribbing, nodes, or tubercles that added strength and hydrodynamic stability. Many species also displayed distinctive suture patterns—complex folding lines where the shell wall joined the septa (internal partitions). These patterns are often preserved in fossils and can be diagnostic for identifying species.

This fossil retains key features of its shell, with visible ribbing and natural mineralisation highlighting its ancient structure. Such details are not only visually striking but also essential for scientific identification.

Depositional Environment and Locality

The Gombe Formation in Nigeria is renowned for its Cretaceous fossil record, preserving remains of ammonites alongside other marine invertebrates. During the Lower Turonian, this region was submerged under warm, shallow seas that provided ideal conditions for marine organisms to thrive. Sediments deposited in these environments often preserved fossils in exceptional detail, as mineral-rich waters replaced organic material and created long-lasting impressions of shell structures.

Collectible Value and Guarantee

• Age: Lower Turonian, Late Cretaceous (93.9–89.8 million years ago)
• Locality: Gombe, Nigeria
• Fossil Type: Ammonite
• Authenticity: 100% genuine fossil with Certificate of Authenticity
• Exact specimen shown in photos (scale cube = 1 cm for sizing)

This ammonite fossil is a rare addition to any collection, combining scientific importance with aesthetic appeal. Its provenance from the Cretaceous deposits of Nigeria makes it especially significant, as fossils from this region are much less common on the collector’s market compared to European or North African examples.
