Fossils & Minerals

A fossilised shell of an ammonite.

Dimensions: approximately 4cm (1.5") x 4cm (1.5") x 1.4cm (0.5"). Sizes may vary as these are natural ammonites.

Ammonites, a form of marine animals, became extinct 65 million years ago along with the dinosaurs. Ammonites are distantly related to modern squids and cuttlefish.

The size of ammonites varied a lot - some were as small as a penny while others reached the size of a tractor tyre. This specimen is from Madagascar and is about 150 million years old.

Dimensions of the box: 4cm each side.

Nautiloid is an extinct marine mollusc from the early Paleozoic era.
This specimen was found in Morocco, it is fossilised in black limestone and is about 400 million years old.
The fossil shows a fragment of nautiloid's shell. It was divided into gas-filled chambers to keep the mollusc buoyant in the water.

Dimensions of the box: 4cm each side.

Teeth are usually the only part of a shark skeleton to survive and fossilise. Shark skeleton is made of cartilage - dense collagenoid tissue - which is soft and is rarely fossilised. Shark teeth are very strong and resilient, hence they can survive millions of years through fossilisation.
Specimens from this set are from Morocco and it is believed they date from the Cretaceous period - more than 100 million years ago.

Chemically dyed. Agate slice available in 3 colours - purple, green and blue.
Agate is a mineral - type of quartz (silica). Agates were formed during millions of years from ancient volcanic lavas. The colour may vary.

Dimensions: approximately 80mm x 40mm x 3mm to 80mm x 20mm x 3mm. Dimensions may vary.

Amethyst is a purple variety of quartz (silica). Its purple colour comes from the strange interaction of iron and aluminium ions inside the crystal of silica.
