The photographs show the exact specimen you will receive, with a 1 cm scale cube included for accurate sizing. Each fossil is supplied with a Certificate of Authenticity, ensuring that it is 100% genuine.

Geological Age and Provenance

The fossil originates from the Lower Callovian stage of the Middle Jurassic, around 166–163 million years ago. At this time, southern Germany was covered by shallow seas that formed part of the extensive Tethys Ocean system. Fine-grained sediments such as mudstones and clays were deposited in these marine environments, producing exceptional conditions for the fossilisation of ammonites. The Lochen area is particularly well-known for its richly fossiliferous Jurassic deposits, which have contributed significantly to paleontological research.

Species Identification and Classification

Macrocephalites compressus belongs to the class Cephalopoda, order Ammonitida, and family Macrocephalitidae. The genus Macrocephalites is a distinctive group of Callovian ammonites known for their relatively large, planispiral shells and compressed whorl sections. The species compressus is an important fossil within Callovian assemblages, often used by geologists to identify specific biozones. Its distinctive shell morphology makes it highly recognisable and valuable for both collectors and researchers.

Morphology and Distinctive Traits

This specimen displays the diagnostic features of Macrocephalites compressus. The shell is compressed with relatively involute coiling, meaning the outer whorls cover much of the inner ones. Strong ribbing extends across the flanks, often curving slightly forward near the ventral area. The ornamentation is bold yet elegant, reflecting adaptations that combined structural reinforcement with hydrodynamic efficiency. The compressed form gives this ammonite a striking appearance and makes it an easily identifiable member of the Macrocephalitidae family.

Scientific and Stratigraphic Importance

Macrocephalites compressus holds particular value as an index fossil for the Lower Callovian stage of the Middle Jurassic. Ammonites of this genus are essential for defining and correlating biozones across Europe and beyond. Their widespread distribution and distinct features provide paleontologists with key insights into cephalopod evolution and Jurassic marine ecosystems. For collectors, owning a specimen of Macrocephalites compressus means holding a piece of fossil evidence that has been central to stratigraphic research and paleontological studies.
