Star Fish Holzmaden
This beautiful pyritised Star Fish was discovered in the oil-shale layer, of the Holzmaden area of Germany. it dates from the jurassic Period, 185 million years old.
The world famous Posidonia Oil-Shale, named after the bi-valve, Posidonia, is known from localities around Holzmaden and Dotternhausen, small villages in Southwestern Germany.
Fossils are found in this 9 metre thick shale, which is fine grained, and characteristically black in colour.
The colour is derived from a high concentration of organic material, and the diffusely distributes pyrite.
The shale was deposited in a marine basin, and the fossils are mostly preserved in perfect condition.
This pyritised Star Fish is no exception with astounding preservation.Starfish first appeared in the fossil record in the Lower Ordovician.
Commonly they have five arms, but some species can have many more.
They are fragile, and do not normally preserve as complete specimens.
These dark fossils are notoriously difficult to photograph, but we have done our best to demonstrate the beauty of this fossil.
It is currently in a frame for better display.
You will not be disappointed with this wonderful fossil.
