Rare Zuercherella latecosta Ammonite Fossil Aptian Cretaceous Russia Genuine Collector Specimen

Description

Rare Zuercherella latecosta Ammonite Fossil from Russia

This listing offers a rare Zuercherella latecosta ammonite fossil, an authentic specimen from the Aptian stage of the Early Cretaceous period, discovered in Russia. Carefully preserved, this fossil provides a fascinating link to marine life that thrived approximately 125 to 113 million years ago. The photographs show the actual specimen you will receive, with a 1 cm scale cube included for precise sizing. Every fossil is supplied with a Certificate of Authenticity, guaranteeing it as a genuine piece of Earth’s history.

Geological Context – Aptian Stage, Early Cretaceous

The Aptian stage forms part of the Early Cretaceous, a period characterised by dynamic geological and biological changes. During this time, global sea levels were rising, producing shallow epicontinental seas that covered much of Europe and Asia, including what is now Russia. These warm, nutrient-rich marine environments supported diverse ecosystems where ammonites flourished alongside belemnites, bivalves, and early marine reptiles.

The Aptian is also notable for its role in major palaeontological studies, marking the expansion of many key ammonite lineages. Fossils from this stage help geologists reconstruct ancient marine conditions, refine biozones, and study evolutionary patterns within the Ammonoidea.

Species Overview – Zuercherella latecosta

The genus Zuercherella is an extinct group of ammonites within the Order Ammonitida, belonging to the Superfamily Deshayesitoidea. The species Zuercherella latecosta is recognised by its characteristic ribbing and coiling style.

Key identifying features include:

• Planispiral coiling, producing a flat, symmetrical shell form.
• Distinct ribbing across the flanks, with ribs that are broader and more widely spaced than in closely related genera.
• A moderately involute whorl structure, giving the shell strength and stability.
• Ornamentation that reflects adaptation to its mid- to shallow-marine habitat.

These morphological traits make Zuercherella latecosta a valuable fossil for both scientific study and private collections.

Scientific Importance and Biozone Relevance

Ammonites such as Zuercherella latecosta are critical to stratigraphy, as they serve as index fossils, enabling geologists to correlate rock formations across vast regions. Their relatively rapid evolution and wide distribution during the Cretaceous allow precise dating of geological strata.

This species, originating from Russian Aptian deposits, highlights the geographic spread of the Deshayesitoidea superfamily and provides insight into the palaeogeography of the Early Cretaceous seas. Its presence within Aptian fossil assemblages makes it particularly valuable for biozone identification and palaeoenvironmental reconstruction.

Collecting Value and Aesthetic Appeal

Fossils of Zuercherella latecosta are not commonly encountered on the market, making this specimen an especially rare collector’s piece. Its well-defined ribbing and natural preservation reveal the intricate shell structure, offering both scientific and aesthetic appeal. Collectors appreciate the genus for its role in Early Cretaceous stratigraphy as well as for its distinctive appearance.

Owning this specimen allows you to connect directly with a marine creature that swam in Cretaceous seas over 100 million years ago, a tangible piece of natural history preserved through deep geological time.
