5.25" Ludwigia bradfordensis Fossil Ammonite – Lower Oxfordian Stage, Jurassic – Calvados, France – Alice Purnell Collection
£ 36.00
This listing features a finely preserved 5.25-inch fossil ammonite of the
species Ludwigia bradfordensis, dating from the Lower Oxfordian stage of the Jurassic period, and discovered in the well-known fossiliferous deposits of Calvados, France. This specimen originates from the esteemed Alice Purnell Collection, known for its premium-quality and well-documented fossils.Ludwigia bradfordensis is an extinct species within the Perisphinctidae family, characterised by a moderately evolute shell with strong, consistent ribbing. These ammonites were free-swimming marine cephalopods that inhabited the warm Jurassic seas around 163 to 157 million years ago. Like other ammonites, they used a system of internal chambers for buoyancy and likely preyed upon small marine creatures.This particular specimen displays clear, sharply defined ribbing and a beautifully coiled spiral shell—hallmarks of the Ludwigia genus. It offers both scientific and aesthetic value for fossil collectors, educators, and enthusiasts.Geological Context: During the Lower Oxfordian Stage of the Late Jurassic, northern France was submerged under a warm epicontinental sea teeming with life. The Calvados region, in Normandy, is celebrated for its fossil-rich marine limestones and marls. These layers provide exceptional preservation of ammonites and help define biostratigraphic zones used to date Jurassic sequences across Europe.Key Details:
