A stunning example of an iridescent ammonite fossil of the species Caloceras johnstoni from North Somerset, UK.

The matrix measures 100 mm (3.95 inches) across and contains a single ammonite, which measures 68 mm (2.7 inches). 

The shell sits in the original limestone matrix in which it was found that has been shaped and has a cut-flat base to allow it to be displayed freely standing by itself.

The ammonite is very well preserved and has been prepared out of the rock to reveal the shell, which displays some beautiful iridescence that changes as the viewing angle changes, with strong green and blue colours. These are the rarest and most sought-after colours in these fossils. The whole piece weighs 190 grams. 

These fossils are highly sought after and very hard to find. They are preserved in the same way as the famous Canadian "Ammolite" ammonites that are turned into valuable gemstones. These fossils make great unusual gifts and each one is totally unique.

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.
