Description

Rare Blandfordiceras wallachi Ammonite Fossil

Presented here is a rare Blandfordiceras wallachi Ammonite Fossil, an exceptional specimen from the Tithonian stage of the Late Jurassic, discovered in the Spiti region of Nepal. Dating back approximately 150 million years, this ammonite is a scientifically important and visually striking fossil. The fossil shown in the photograph is the exact specimen you will receive, pictured alongside a 1 cm scale cube for accurate size reference. Each fossil is guaranteed authentic and comes with a Certificate of Authenticity for complete reassurance.

Geological Context – Spiti Region, Nepal

The Spiti Valley, situated in the high Himalayas, is world-renowned for its extensive exposures of Mesozoic sediments. During the Late Jurassic, this area formed part of a vast marine basin connected to the Tethys Ocean. Sediments deposited here consist of limestones and marls that have preserved a rich fossil record, including ammonites of international importance. The Tithonian stage marks the final subdivision of the Jurassic period, just before the transition into the Cretaceous. Fossils from this horizon offer valuable insight into both evolutionary developments and paleoenvironmental conditions at the close of the Jurassic.

Species Overview – Blandfordiceras wallachi

This fossil has been identified as Blandfordiceras wallachi, a species within the genus Blandfordiceras, belonging to the order Ammonitida, superfamily Perisphinctoidea, and family Perisphinctidae. Ammonites of this genus are characterised by their involute shells with compressed whorls and finely ribbed ornamentation. The ribs often curve forward across the flanks and may bifurcate, creating an elegant and diagnostic pattern.

The distinctive morphology of Blandfordiceras wallachi makes it highly recognisable to specialists and an important reference taxon in ammonite studies. Its shell features not only provide aesthetic appeal but also serve as critical tools for paleontologists in correlating and dating Jurassic rock layers.

Paleontological Importance

Ammonites such as Blandfordiceras wallachi are prized as index fossils. Their relatively rapid evolutionary turnover and widespread geographic distribution allow geologists to subdivide the Tithonian stage into detailed biozones, which can then be used to correlate rock sequences across continents. This makes specimens from Spiti particularly valuable, as the Himalayas preserve sequences essential for global Jurassic stratigraphy.

From an ecological perspective, Blandfordiceras occupied a role as a fast-moving nektonic predator, actively swimming in the open ocean and feeding on small invertebrates. Its shell structure provided both hydrodynamic efficiency and structural reinforcement, adaptations that contributed to the evolutionary success of ammonites during the Mesozoic era.

Collector’s and Educational Value

The rarity of Blandfordiceras wallachi ammonite fossils on the market, combined with their importance in Jurassic stratigraphy, makes this specimen especially desirable. Its natural preservation captures the delicate ribbing and shell form, making it an attractive display piece. At the same time, it holds strong scientific and teaching value, illustrating ammonite evolution and biostratigraphy in the late Jurassic world.
