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

The matrix measures 105 mm (4.2 inches) across and contains a single complete ammonite that measures 30 mm (1.2 inches), making it a juvenile of this species, and a second piece of shell from a much larger ammonite.

The shell sits in the original limestone matrix in which it was found that has been shaped around the ammonite. 

The ammonite is very well preserved and has been prepared out of the rock to reveal the shell, which displays some subtle iridescence that changes as the viewing angle changes with red and bronze colours dominating. The whole piece weighs 70 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.
