A stunning example of a cut and polished calcite ammonite fossil of the species Asteroceras stellare from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The piece of ammonite measures 155 mm (6.1 inches) tall, which is a very good size for this species. The piece consists of part of the ammonite that has been cut with a diamond saw and polished to show off the crystalline structure of the shell that makes these fossils famous. The internal gas buoyancy chambers of the shell are well exposed and show the naturally occuring brown calcite crystals that grow inside the empty chambers over geological time. Many hours of work have gone into making this into a display piece of the highest quality. A great example of an uncommon species and impressive in the flesh. The fossil weighs 1915 grams and has a cut flat base to allow it to stand freely on its own for display. These are very sought after ammonites from this world-famous location, especially large display pieces like this example. This one would look great for a unique interior design project.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
