Tragophylloceras Fossil Ammonite Large Bowl Prepped Jurassic Coast Charmouth Dorset UK – Genuine Green Ammonite Beds Lower Lias Specimen

Authentic Tragophylloceras Fossil Ammonite from the Jurassic Coast, Dorset This impressive Large Bowl Prepped Tragophylloceras Fossil Ammonite originates from the Green Ammonite Beds of the Lower Lias Formation, a globally recognised fossil-rich deposit along the Jurassic Coast at Stonebarrow Cliff, Charmouth, Lyme Regis, Dorset, UK. Carefully discovered by our experienced fossil hunters Alister and Alison on 01 November 2025, this specimen captures a remarkable snapshot of ancient marine life dating back approximately 190–195 million years, during the Early Jurassic (Sinemurian) Stage. The fossil has been expertly cleaned, prepped, and treated by Alison, ensuring it retains its authentic structure and visual appeal. Geological and Scientific Context Tragophylloceras belongs to the family Lytoceratidae, within the superfamily Lytoceratoidea and the order Ammonitida—a group of extinct cephalopods closely related to modern squid and octopus. The genus is distinguished by its finely ribbed, involute shells and smooth, rounded whorls, which often exhibit subtle mineralisation and pyritisation depending on the host matrix. The Green Ammonite Beds, part of the Lower Lias, are celebrated for their rich concentration of ammonites preserved in distinctive greenish-grey mudstones. These sediments were deposited in low-energy, shallow marine environments, where calm Jurassic seas allowed fine-grained sediments to entomb marine organisms quickly, preserving their exquisite detail. During the Sinemurian–Pliensbachian boundary interval, Tragophylloceras species diversified widely and became important biostratigraphic markers. Their consistent morphology and rapid evolutionary turnover allow geologists to use them to identify and correlate specific layers in Jurassic strata across Europe. Specimens from the Charmouth and Lyme Regis regions are among the finest known, combining both scientific value and aesthetic beauty. Morphology and Key Features This fossil displays the characteristic bowl-prepped presentation, exposing the full coiling of the ammonite in stunning relief. The shell shows well-defined sutures and subtle ribbing, with an elegant spiral and slightly compressed whorl section typical of the genus. The detailed suture lines and chamber structures provide insight into how this ammonite’s shell evolved to balance buoyancy and strength. The preservation is exceptional, showing both the internal structure and external ornamentation, giving a true sense of the living organism’s hydrodynamic form as it once moved through Jurassic seas. Preparation and Provenance Every specimen offered is 100% genuine and professionally authenticated. This particular fossil was discovered and prepared entirely by our in-house team, ensuring full traceability and expert care throughout its handling. Alison’s precise laboratory preparation techniques—careful mechanical cleaning and consolidation—have preserved the ammonite’s natural integrity while enhancing its visual clarity.
