Strenoceras quenstedti Ammonite Fossil Bajocian Germany with COA

Description

Genuine Strenoceras quenstedti Ammonite Fossil

This listing is for the genuine ammonite fossil shown in the photographs, identified as Strenoceras quenstedti. It comes from Gruibingen in Baden-Württemberg, Germany, and dates to the Bajocian Stage of the Middle Jurassic. The Bajocian spans approximately 170.3 to 168.3 million years ago. This is an authentic fossil specimen, not a cast, replica, or modern reproduction, and the photographs show the exact piece that will be supplied.

Bajocian Marine Geology

Ammonites were extinct marine cephalopods related to living squid, cuttlefish, octopus, and nautilus. Their coiled shells were divided internally by septa into a succession of chambers. The living animal occupied the final body chamber, while the earlier chambers formed part of a buoyancy system that helped control movement through the water. Suture lines developed where the septa met the shell wall and can assist in ammonite identification. Because ammonites evolved rapidly and were distributed widely, their fossils are valuable index fossils used to correlate and date Jurassic marine sedimentary rocks.

Strenoceras quenstedti Identification

The supplied identification for this specimen is Strenoceras quenstedti. Strenoceras is a recognised Bajocian ammonite genus associated with distinctive shell ornament and important biostratigraphic intervals. Depending on preservation and growth stage, specimens may show coiled whorls, strong ribs, tubercles, shell profile, body chamber, sutural detail, internal mould, or mineral replacement. The name niortense is widely used in Bajocian ammonite study and biostratigraphy. Please examine every image carefully because they show the precise morphology, condition, and natural surfaces of this exact fossil.

Gruibingen Baden-Württemberg Provenance

Gruibingen lies in Baden-Württemberg, a region of southern Germany known for fossil-bearing Jurassic sedimentary rocks. These strata record ancient marine environments in which ammonite shells and other remains accumulated on or within seabed sediment. Over millions of years the sediment compacted into rock, while mineral-rich water preserved or replaced original shell material. Later uplift and erosion exposed the fossil-bearing beds again. Matrix, mineral colour, weathering, incomplete areas, exposed internal material, veining, and small chips are natural parts of the specimen’s geological history rather than manufacturing defects.

Exact Fossil for Collection or Study

You will receive the exact Strenoceras quenstedti ammonite shown in the photographs, with no substitution. The first image is the main display view and the second provides another angle for assessing shell form, ornament, matrix, and preservation. Please refer to the images for full sizing and scale. This carefully chosen specimen is suitable for a Middle Jurassic ammonite collection, German fossil display, natural history cabinet, geology teaching set, scientific study resource, or distinctive gift for a collector, student, or fossil enthusiast. Its documented Bajocian age and Gruibingen provenance add valuable scientific and historical context.

Certificate of Authenticity

A generic Certificate of Authenticity is included with the fossil. It records the supplied identification, geological age, and locality information and carries our lifetime guarantee of authenticity. The specimen will be packed carefully and securely for dispatch. Every natural feature visible in the photographs belongs to the actual fossil you will receive. This genuine Strenoceras quenstedti ammonite offers an attractive and scientifically informative connection to the Middle Jurassic seas of southern Germany and to the ammonite succession used for detailed Bajocian correlation.
