£ 36.00
AUTHENTIC PICTONIA BAYLEI FOSSIL AMMONITE FROM WILTSHIRE, UKThis listing offers a rare and scientifically significant Pictonia baylei fossil
ammonite, collected from the Lower Kimmeridgian stage of the Jurassic, Wootton Bassett, Wiltshire, United Kingdom. Known for its distinctive coiling and ribbed ornamentation, Pictonia baylei is a key ammonite species for the study of Jurassic stratigraphy. The specimen shown in the photographs is the exact fossil you will receive, with a 1 cm scale cube included for accurate sizing.All of our fossils are 100% genuine specimens and are supplied with a Certificate of Authenticity, making them ideal for collectors, educators, and enthusiasts of natural history. GEOLOGICAL AGE AND LOCALITYThis fossil dates to the Lower Kimmeridgian stage of the Late Jurassic (approximately 157–152 million years ago). The famous exposures of Wootton Bassett in Wiltshire are among the most productive Jurassic fossil localities in the UK, renowned for yielding ammonites of exceptional quality and diversity.The Kimmeridgian represents one of the key stages of the Jurassic Period, marked by extensive marine environments. Ammonites such as Pictonia baylei thrived in these seas, leaving behind beautifully preserved shells that today act as windows into Earth’s deep past. FOSSIL TYPE AND CLASSIFICATION
• Species: Pictonia baylei
• Genus: Pictonia
• Family: Aulacostephanidae
• Superfamily: Perisphinctoidea
• Order: AmmonitidaPictonia baylei is a distinctive ammonite, recognised for its diagnostic ribbing and coiling style. As a member of the Aulacostephanidae family, it is an important index fossil, widely used in correlating Jurassic marine strata across Europe. MORPHOLOGICAL FEATURESThe specimen displays the key features of Pictonia baylei:
• A moderately involute coiled shell with broad whorls.
• Strong, regularly spaced ribs crossing the flanks of the shell.
• A rounded venter (outer shell margin), often carrying continuation of ribbing.
• Clear suture lines where the inner shell walls met the outer surface.These morphological traits not only give the ammonite its striking appearance but also provide crucial identification markers for geologists working on Jurassic biostratigraphy. SCIENTIFIC AND COLLECTOR IMPORTANCEPictonia baylei is a highly valuable biozonal ammonite, forming part of the key Baylei Zone within the Lower Kimmeridgian. Its presence enables geologists to pinpoint precise layers within Jurassic marine deposits, making it indispensable for stratigraphic work.For collectors, this ammonite offers the opportunity to own a classic specimen from one of Britain’s most celebrated fossil localities. Its rarity, preservation, and historical importance make it a striking centrepiece in any fossil collection, as well as an educational example of Jurassic marine life. DEPOSITIONAL ENVIRONMENTDuring the Kimmeridgian, the region around present-day Wiltshire was part of a warm, shallow sea rich in marine life. Ammonites, bivalves, and marine reptiles flourished in these waters, leaving behind fossil-rich deposits of clay and limestone. The fine sediments of Wootton Bassett created ideal conditions for preserving ammonites such as Pictonia baylei in remarkable detail, allowing modern collectors to appreciate both their natural beauty and scientific importance. GUARANTEE OF AUTHENTICITYAll fossils offered are 100% genuine specimens, carefully selected for their quality, rarity, and scientific value. Each comes with a Certificate of Authenticity, ensuring confidence in its provenance. The photographs show the exact fossil ammonite you will receive, with scale references included.This Pictonia baylei fossil ammonite from the Lower Kimmeridgian of Wootton Bassett, Wiltshire is a rare and highly collectible piece of Britain’s Jurassic heritage – a true treasure of natural history.
