Macrocephalites Ammonite Fossil Jurassic Latton Wiltshire UK Genuine Authentic COA
£ 12.60
AUTHENTIC JURASSIC FOSSIL FROM WILTSHIRE, UKThis Macrocephalites ammonite fossil is a genuine specimen from the Lower
Callovian stage of the Middle Jurassic, discovered at Latton in Wiltshire, United Kingdom. Carefully selected for its preservation and scientific significance, this fossil highlights the remarkable diversity of ammonites during the Jurassic period. The photographs show the exact specimen you will receive, with a 1 cm scale cube included for accurate sizing. Every specimen comes with a Certificate of Authenticity, guaranteeing it is 100% genuine. GEOLOGICAL AGE AND PROVENANCEDating back approximately 166–163 million years, this ammonite was formed during the Lower Callovian stage of the Jurassic. At that time, Wiltshire was covered by shallow epicontinental seas connected to the Tethys Ocean. Fine sediments deposited in these environments created the perfect conditions for the preservation of marine life, particularly ammonites. Latton and the surrounding area are renowned for yielding fossils of exceptional quality from the Cornbrash and related Jurassic formations, making them key localities for British paleontology. SPECIES IDENTIFICATION AND CLASSIFICATIONMacrocephalites belongs to the class Cephalopoda, order Ammonitida, superfamily Stephanoceratoidea, and family Macrocephalitidae. The genus is one of the most iconic ammonite groups of the Callovian stage, known for its large, compressed shells and bold ribbing. These ammonites are particularly important to paleontologists because of their abundance and wide distribution, which makes them excellent index fossils for dating and correlating Lower Callovian strata across Europe and beyond. MORPHOLOGY AND DISTINCTIVE TRAITSThis specimen displays the characteristic features of the Macrocephalites genus. Its shell is tightly coiled in a planispiral form with compressed whorls. Strong ribs sweep across the flanks and often bifurcate as they approach the ventral side, giving the ammonite a distinctive and bold ornamentation. The ribs not only added structural reinforcement to the shell but also played a role in maintaining buoyancy and stability in the water column. The symmetry, ribbing pattern, and overall size of Macrocephalites make it one of the most recognisable and desirable Callovian ammonites. SCIENTIFIC AND STRATIGRAPHIC IMPORTANCEMacrocephalites ammonites are widely regarded as essential tools for Jurassic stratigraphy. Their relatively short evolutionary turnover, distinctive morphology, and global distribution make them highly reliable index fossils. Specimens such as this are critical for defining biozones within the Lower Callovian stage and for correlating rock layers across Europe. For collectors, this fossil offers not just aesthetic appeal but also direct ties to the scientific framework used to understand Earth’s history during the Jurassic. CONDITION AND PRESENTATIONThis ammonite has been carefully prepared to reveal its natural details, with ribbing and whorl structure clearly visible. It has not been artificially enhanced, ensuring its authenticity and natural appeal. The images show the exact specimen you will receive, ensuring full transparency and confidence in your purchase. This is a one-of-a-kind piece, making it a superb addition for both display and study. GUARANTEE OF AUTHENTICITYAll of our fossils are 100% genuine, responsibly sourced, and scientifically identified. Each specimen is supplied with a Certificate of Authenticity. This Macrocephalites ammonite fossil from Latton, Wiltshire, is a rare and scientifically significant piece of Jurassic natural history, making it an exceptional addition for fossil collectors, natural history enthusiasts, and educational collections.
