This pyrite (pyritized) fossil is from Le Clapier, Cornus, Aveyron, Occitane, France. This is a well known fossil collecting area in the south of France. The area has cliffs which contain various exposed sediments that date back to the Cambrian Series. This is a fossil ammonite, species Amaltheus, dating to about 190 million years ago in the Jurassic Period (Pliensbacian Age). It is both a beautiful pyrite specimen as well as an exceptional fossil. The well defined ammonite was found in situ in a fossil rich shale. It was then cleaned and coated in a protective lacquer. The matrix measures 69 x 45 x 16 mm. The ammonite is 28 mm across.
