This auction is a stunning example of an iridescent ammonite fossil of the species Caloceras johnstoni from North Somerset, UK. 

The piece of limestone matrix measures 172 mm (6.75 inches) tall and contains a large partial ammonite that measures 73 mm (2.85 inch) across, is well preserved, and has been prepared out of the rock to reveal the details. The shell displays some stunning iridescence with the colours changing depending on the angle that the fossil is viewed at with red, copper, and green tones appearing at certain angles. The colours also change as the type of light changes. The ammonite still sits in the original limestone matrix in which it was found that has a cut-flat base to allow it to stand on its own for display. The whole piece weighs 90 grams.

Around 200 million years old (Hettangian, Early Jurassic), this fossil would make a wonderful addition to any collection.

Combined shipping: I offer combined shipping on all of my fossils. If you wish to purchase multiple fossils, just send a message to let me know and I can hold any order open for up to 25 days from the first auction win/purchase for more fossils to be added to the order. After you have finished adding items to an order, let me know and I will combine the shipping to the lowest amount possible for your items.

The shipping cannot be combined automatically due to the large variation in weight of the fossils and the costs of different weight classes of the Royal Mail.
