Pair of Jurassic Brittle Star (Sinosura) Fossils - Solnhofen

This is a Jurassic aged brittle star (Sinosura kelheimense) from the famed Solnhofen Limestone of Germany.

The Solnhofen limestone is a famous Lagerstätte in Germany that offer amazing preservation of Upper Jurassic fossils. It is where one of the most famous fossils of all time, Archaeopteryx, was found. The fine grained limestone makes excellent building materials which has led to heavy quarrying over the past two centuries, which has resulted in some amazing fossils being unearthed.

This area represented an archipelago at the edge of a sea. Due to high salt content, the lowest levels in the water column could not support much life and were largely devoid of oxygen. This lack of scavengers on the bottom of the sea led to amazing preservation of the fauna found there.
