Natural History - Fossils

Petraster is an extinct genus of Ordovician-period starfish, often found in Morocco's Anti-Atlas region. These echinoderms typically feature five short, wide arms and a large central disc. They are generally identified by their Asteroid-like shape, often featuring reddish-orange coloring due to iron oxidation.

A fossil Ophiurodea sp. brittle star in an irregular matrix. Brittle stars are echinoderms with long, flexible arms that are closely related to starfish. From the Ordovician period. 

The delicate nature of these creatures makes successful fossilisation less likely, so they are quite rare.

Size: 110mm, 300g

Condition: Fine condition

Provenance: Found El Kaid Errami, Tafilalt, Morocco, North Africa; froman old German collection

This trilobite is from the family Odontopleuridea and the genus Leonapsis whose exoskeleton tends to be very spine-like. Examples of this trilobite have been found on all continents except Antarctica. Our example has a slight repair and comes on its stone matrix. It was found in the Atlas Mountains, Morocco in the Hamar L'Aghdad limestone areas. 

Prov: From an old Cambridgeshire collection.

Well preserved coniferous seed cones are relatively rare, this agatizes cone comes from what is now the Western Sahara desert in Morocco, which tells us that at one time it must have been heavily forested. Fossilisation takes place over long periods of encapsulation within silt layers underwater or being covered quickly by ash, so that oxygen is deprived and in turn deterioration and decomposition is slowed, allowing miniralisation to take place instead.

Size: 40mm x 17mm, 13.8g

Condition: Well preserved with good scale definition but some encrustations adhering. Will be supplied in a small dispaly box, it can be removed.

Prov: From an old Bristol collection acquired in the 50's.
