RARE: Reineckia anceps Fossil Ammonite (5.5")Geological Age: Middle Callovian, Middle Jurassic (~165 to 164 million years
ago)Location Found: La Grimaudière, Vienne, Nouvelle-Aquitaine, FranceFossil Type: Ammonite (Extinct Marine Cephalopod)Species: Reineckia ancepsOrder: AmmonitidaSuperfamily: StephanoceratoideaFamily: Reineckeiidae Specimen Overview:This rare 5.5-inch ammonite fossil is Reineckia anceps, an elegant and scientifically important species from the Middle Callovian stage of the Jurassic. Discovered in La Grimaudière, a well-known fossil site in Vienne, France, this specimen is a fine example of the marine life that thrived in Europe's Jurassic seas.The photo displays the actual fossil you will receive. A 1cm scale rule cube is included in the image for accurate sizing. Please refer to the photo for full size, preservation, and detail. Geological Context & Depositional Environment:The Middle Callovian was characterised by extensive shallow marine basins across Western Europe. The region around La Grimaudière represents one such basin, where calcareous clays and silts created a favourable environment for the preservation of marine organisms.This fossil may come from within the Reineckia anceps Biozone, which is a key ammonite biostratigraphic marker for the Middle Callovian, particularly in Western Europe. These strata help correlate marine sequences across the Jurassic Tethys realm. Morphology & Notable Features:Reineckia anceps exhibits an involute shell with smooth inner whorls and strong, rounded primary ribs that often bifurcate as they cross the flanks. Its shell is moderately compressed with a relatively narrow venter, giving it a streamlined yet ribbed appearance. The ribbing and whorl structure provide excellent examples of Callovian ammonite evolution.This 5.5" specimen is notable for its well-preserved ornamentation and defined ribbing—traits that make it both visually striking and scientifically valuable. Authenticity & Guarantee:All our fossils are 100% genuine specimens and come with a Certificate of Authenticity. Every piece is professionally prepared, stabilised, and carefully chosen for its quality and educational or display potential. Perfect For:
• Fossil collectors and natural history curators
• Geological educators and academic research
• Decorative and educational displays
• Gifts for palaeontology enthusiastsCapture a moment from the Jurassic seas with this stunning Reineckia anceps ammonite from the classic Middle Callovian strata of Vienne, France—a prized addition to any fossil collection!
