Description
Genuine Metahaploceras nodosiusculum Ammonite Fossil
This listing is for a genuine Metahaploceras nodosiusculum ammonite fossil from Geisingen, Baden-Württemberg, Germany. Dating from the Kimmeridgian Stage of the Upper Jurassic, this specimen represents a collectible European ammonite from the ancient marine deposits of southern Germany.
Metahaploceras nodosiusculum is an attractive and scientifically interesting ammonite species, valued by collectors for its named identification, Upper Jurassic age, and connection with the classic fossil-bearing rocks of Baden-Württemberg. This fossil is a carefully chosen piece, and the photograph shows the actual specimen you will receive. Full sizing can be seen in the photo.
Geology, Age and German Locality
This ammonite comes from Geisingen, in Baden-Württemberg, southern Germany. This region is part of a wider area famous for Jurassic sedimentary rocks, particularly the marine limestones, marls, and associated fossil-bearing beds of the Swabian and southern German Jurassic successions. These deposits have produced a wide range of ammonites and other marine fossils, making the area an important locality for European palaeontology.
The fossil is Kimmeridgian in age, placing it within the Upper Jurassic, approximately 157 to 152 million years old. The Kimmeridgian was a time when warm shallow seas covered large areas of Europe, including what is now southern Germany. These seas supported diverse marine ecosystems and produced many important ammonite faunas used by geologists to date and correlate rock layers.
During this part of the Jurassic Period, the region now known as Baden-Württemberg lay beneath marine waters connected to broader European shelf seas. Sediments accumulated on the seafloor and preserved the remains of ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, fish, sharks, and other marine organisms. Fossils from this region are especially collectable because they combine strong geological provenance with a long history of scientific study.
Fossil Type and Species Details
Metahaploceras nodosiusculum was an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish, octopus, and nautilus. Like other ammonites, it had a coiled external shell divided internally into chambers. The living animal occupied the final body chamber, while the earlier chambers helped regulate buoyancy as it moved through the Jurassic sea.
The genus Metahaploceras forms part of the diverse Upper Jurassic ammonite fauna of Europe. Ammonites of this type are generally recognised by their planispiral coiled shell, defined whorl shape, and ornament that may include ribbing, growth lines, or nodose features depending on preservation and growth stage. The species name nodosiusculum reflects the nodular or subtly ornamented character associated with this ammonite group.
Scientific classification places Metahaploceras within Phylum Mollusca, Class Cephalopoda, Subclass Ammonoidea, and Order Ammonitida. As with many Jurassic ammonites, the shell form, ribbing, whorl section, and suture pattern are important features used in identification. These details make specimens such as Metahaploceras nodosiusculum appealing to collectors who value named, locality-specific fossil material.
Upper Jurassic Marine Environment
During the Kimmeridgian, southern Germany was part of a warm marine shelf environment. The seas were home to a rich community of swimming, drifting, crawling, and bottom-living organisms. Ammonites such as Metahaploceras nodosiusculum lived in the water column, using their chambered shells for buoyancy control while feeding and moving through the marine ecosystem.
The same Jurassic seas supported belemnites, bivalves, brachiopods, gastropods, echinoids, fish, sharks, and marine reptiles. Fine sediment, carbonate mud, and shell-rich material accumulated across the seafloor, eventually becoming the fossil-bearing rocks seen in southern Germany today. These conditions helped preserve ammonites and other marine remains, creating one of Europe’s most important Upper Jurassic fossil records.
Ammonites are especially valued in palaeontology because they evolved quickly and spread widely through ancient seas. This makes them excellent guide fossils for understanding geological time, comparing rock layers, and reconstructing past marine environments. A specimen from Geisingen offers both attractive display value and strong educational interest.
Collectible German Jurassic Ammonite
This Metahaploceras nodosiusculum ammonite fossil is an excellent specimen for collectors of German fossils, European ammonites, Upper Jurassic fossils, Kimmeridgian ammonites, and scientifically labelled natural history specimens. Its named species, Geisingen locality, Baden-Württemberg origin, and classic Jurassic ammonite form make it a desirable addition to a fossil collection, educational display, natural history cabinet, or geology-themed gift selection.
This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. The photograph shows the actual fossil you will receive, making this a carefully selected and accurately represented collector’s piece from the Upper Jurassic marine deposits of Geisingen, Baden-Württemberg, Germany.
