£ 14.40
AUTHENTIC JURASSIC FOSSIL FROM OXFORDSHIRE, UKThis Cadoceras apertum ammonite fossil is a genuine specimen from the Callovian
stage of the Middle Jurassic, discovered in Stanton Harcourt, Oxfordshire, United Kingdom. Carefully selected for its quality preservation and distinctive features, this fossil represents both scientific importance and natural beauty. The photographs show the exact specimen you will receive, with a 1 cm scale cube provided for accurate sizing. Every specimen is supplied with a Certificate of Authenticity, guaranteeing it is 100% genuine. GEOLOGICAL AGE AND PROVENANCEDating back approximately 166–163 million years, this ammonite comes from the Callovian stage of the Jurassic Period. At this time, the Stanton Harcourt region was part of a shallow marine environment connected to the Tethys Ocean. Warm epicontinental seas covered much of Oxfordshire, where fine-grained sediments accumulated, creating perfect conditions for the preservation of ammonites and other marine life. The area is well known for producing high-quality Jurassic fossils, making it an important locality for paleontological study. SPECIES IDENTIFICATION AND CLASSIFICATIONCadoceras apertum belongs to the class Cephalopoda, order Ammonitida, superfamily Perisphinctoidea, and family Cardioceratidae. Members of the genus Cadoceras are particularly notable for their strongly ribbed shells and distinctive whorl structures. The species apertum is an important part of the Callovian ammonite assemblages of northwestern Europe and is highly valued for its role in biostratigraphic studies. Its occurrence helps paleontologists define ammonite zones that are essential for correlating Jurassic rock layers across large regions. MORPHOLOGY AND DISTINCTIVE TRAITSThis specimen displays the key features of Cadoceras apertum. The shell is planispiral, with moderately involute whorls and strong ribbing that sweeps symmetrically across the flanks. The ribs are bold and evenly spaced, giving the fossil a striking ornamentation that is easily recognisable. The whorl section is rounded, with ornamentation that reinforced the shell and provided hydrodynamic efficiency. These distinctive traits make apertum a particularly attractive fossil for collectors while also serving as clear diagnostic markers for scientific study. SCIENTIFIC AND STRATIGRAPHIC IMPORTANCECadoceras apertum is widely regarded as an important index fossil for the Callovian stage. Its restricted stratigraphic range and distinctive morphology allow geologists to correlate Jurassic strata with high precision. This species plays a crucial role in refining the Jurassic timescale, making it valuable both scientifically and historically. Fossils like this also help reconstruct the marine ecosystems of the Middle Jurassic, shedding light on ammonite evolution and the biodiversity of the Tethyan seas. CONDITION AND PRESENTATIONThis specimen has been carefully prepared to preserve its natural features, with ribbing, whorl structure, and overall shell morphology clearly visible. It has not been artificially enhanced or altered, ensuring that its authenticity is maintained. The photographs show the actual ammonite you will receive, ensuring complete confidence and transparency in your purchase. Its preservation quality makes it suitable for both display and research purposes. GUARANTEE OF AUTHENTICITYAll of our fossils are 100% genuine, responsibly sourced, and scientifically identified.
