A large black ammonite still stuck in the parent rock, with a small shell trapped at the back of the parent rock.

The ammonite was carefully carved out of the rock, so the outer shell was left natural, so that the ribbed, original dark outer shell can now be shown. This type of ammonite is usually between 3 and 10 cm in size. However, much larger specimens with a diameter of up to 80 cm have also been found. The larger the ammonite, the rarer it is to find. This one has a diameter of 18.5 cm and the knife block made of Nero Impala has gold plating, in a kind of cave at the back and immediately visible at the front.

Fossil: Ammonite Goniatitida
Location: Nepal
Formation: Upper Jurassic, Oxfordian
Age: approx. 150 million years
Total size: approx. 18.5cm


Ammonites are an extinct group of cephalopods that lived in the sea. There were around 40,000 different species, the largest of which grew to two meters. This ammonite was found in Madagascar and dates back to the Lower Cretaceous period. This makes them around 150 million years old. It's just unbelievable... Ammonites became extinct around 65 million years ago, around the same time as the dinosaurs. The shape of their shells resembles a spiral tube. The animals only lived in the end of the tube. The remaining chambers were filled with air and made it easier to sink and rise in the water.

Nero Impala impresses at first glance with its elegant, uniform appearance. This natural stone is an anthracite-colored to black natural stone and belongs to the Gabbro rock family. Furthermore, from a petrological point of view, it is a Norite.
