16" Limestone Clock With Fossil Fish & Dendrites - Solnhofen Limestone

This is a really cool clock made out of limestone slabs from the Solnhofen Limestone in Germany. There are four slabs of limestone with small (2-3" long) fossil fish on them, and many of the slabs also have dendrites. The dendrite are crystalized manganese that have grown in a tree-like, branching form in between the layers of the rock. People often mistake them for plant fossils, but they are mineral deposits.

The Solnhofen limestone is a famous, Upper Jurassic Lagerstätte in Germany. 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 spectacular fossils being unearthed including fossil dragonflies, fish, pterosaurs, shrimp, horseshoe crabs, etc.

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 oxygen and scavengers on the bottom of the sea led to beautiful fossil preservation.
