Description

Rare Parapallasceras pseudocontiguus Ammonite Fossil

This listing offers a rare Parapallasceras pseudocontiguus Ammonite Fossil from the Tithonian stage of the Late Jurassic, found in Bishberg, Germany. Estimated to be around 150 million years old, this ammonite represents an important and distinctive taxon from the closing chapter of the Jurassic period. Each specimen is 100% genuine and supplied with a Certificate of Authenticity. The fossil shown in the photographs is the exact piece you will receive, with a 1 cm scale cube provided for accurate size reference.

Geological Context – Bishberg, Germany

The fossil originates from the Tithonian deposits of Bishberg, one of the most significant localities in Germany for Late Jurassic ammonites. During the Tithonian, this region formed part of the shallow marine environments connected to the Tethys Ocean, where fine limestones and marls accumulated. These sediments created excellent conditions for the preservation of ammonites and other marine organisms. The Tithonian stage, the last subdivision of the Jurassic, is crucial for understanding the evolutionary history of ammonites leading into the Cretaceous. Bishberg fossils are particularly valuable because they provide a well-documented faunal record, widely used in biostratigraphic research across Europe.

Species Overview – Parapallasceras pseudocontiguus

This specimen belongs to Parapallasceras pseudocontiguus, part of the order Ammonitida, superfamily Perisphinctoidea, and family Perisphinctidae. Ammonites of this genus are known for their moderately involute shells, strong ribbing, and distinctive ornamentation. In Parapallasceras pseudocontiguus, the ribs are often bold and bifurcate across the flanks, creating an attractive branching pattern that is both diagnostic and visually striking.

These features highlight the adaptability of the species in its marine environment. The coiling and ribbing provided both structural reinforcement and hydrodynamic efficiency, allowing the ammonite to move actively through the open seas. Its morphology reflects the ecological versatility that made ammonites such successful cephalopods throughout the Mesozoic.

Paleontological Importance

Parapallasceras pseudocontiguus is a key index fossil for the Tithonian stage. Its distinct morphology and stratigraphic range make it extremely valuable for defining ammonite biozones that allow geologists to correlate rock sequences across wide areas. Ammonites like this are central to Jurassic chronostratigraphy and are widely referenced in paleontological studies.

This species also illustrates evolutionary experimentation during the Late Jurassic. The strong ribbing and robust shell ornamentation of Parapallasceras demonstrate adaptations to predation pressures and environmental conditions of the time. Its presence in Bishberg deposits provides insight into the diversity and distribution of ammonites at the very end of the Jurassic.

Collector’s and Educational Value

This Parapallasceras pseudocontiguus ammonite fossil is a rare and scientifically important specimen. Its bold ribbing and attractive form make it a superb display piece, while its biostratigraphic value ensures it is equally significant for academic and teaching collections. For fossil enthusiasts, this represents an outstanding opportunity to acquire an ammonite that is both rare and highly sought after.
