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

The matrix measures 165 mm (6.5 inches) across and contains a large partial ammonite that measures 105 mm (4.2 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 stand freely for display in multiple orientations.

The ammonite is very well preserved and has been prepared out of the rock to reveal the shell. The shell displays some beautiful iridescence with flashes of red, gold, and copper that appear as the viewing angle changes. 

These fossils are preserved in the same way as the famous Canadian "Ammolite" ammonites that are turned into valuable gemstones. The fossil weighs 480 grams.

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