Geological Age and Provenance

Dating back approximately 197–190 million years, this fossil was formed during the Upper Sinemurian stage of the Lower Jurassic. At this time, Stowey and the surrounding Somerset region were submerged beneath shallow seas on the northern margin of the Tethys Ocean. Fine-grained sediments of mudstone and silt slowly accumulated, preserving ammonites and other marine fauna in remarkable detail. The Lower Lias formations of Somerset are world-renowned for their rich fossil record, with ammonites such as Paltechioceras dedicatum playing a crucial role in defining stratigraphic zones.

Species Identification and Classification

Paltechioceras dedicatum belongs to the class Cephalopoda, order Ammonitida, superfamily Eoderoceratoidea, and family Echioceratidae. The genus Paltechioceras is characterised by compressed, planispiral shells with fine ribbing and slender whorls. The species dedicatum is particularly significant as it occurs within Upper Sinemurian ammonite assemblages used in stratigraphy to refine the geological timescale. Its distinct morphology makes it an identifiable and highly valued fossil among collectors of early Jurassic ammonites.

Morphology and Distinctive Traits

This specimen displays the diagnostic features of Paltechioceras dedicatum, including compressed whorls, finely ribbed ornamentation, and elegant planispiral coiling. The ribs are delicate yet well-defined, running symmetrically across the shell flanks to create an attractive pattern. These features represent adaptations that supported both shell strength and hydrodynamic function in Jurassic seas. The fossil’s fine preservation allows these details to be clearly appreciated, making it a particularly appealing example of its kind.

Scientific and Stratigraphic Importance

Ammonites such as Paltechioceras dedicatum are crucial to paleontology and geology, as they act as index fossils that allow geologists to date and correlate sedimentary rock layers. Their presence in Upper Sinemurian horizons helps define ammonite biozones, which form the backbone of Jurassic stratigraphy. These fossils also provide insights into evolutionary trends within the family Echioceratidae, helping scientists to reconstruct marine ecosystems following the end-Triassic extinction. Collectors value them for their combination of rarity, beauty, and scientific relevance.

Condition and Presentation

The fossil has been carefully prepared to preserve its natural features while showcasing its diagnostic traits. Ribbing, shell form, and whorl structure are clearly visible, demonstrating the elegance of this early Jurassic ammonite. This is not a cast or reproduction but a genuine, one-of-a-kind specimen.
