3.9" Pleurosaurus Skull - Solnhofen Limestone, Germany

 
 
This is a rare, 3.9" long skull of a Pleurosaurus from the Solnhofen Limestone in Germany. It's centered on a nice slab of limestone which has been backed with epoxy due to it being rather thin. There is one repaired crack running through the rock.

Pleurosaurus was an Upper Jurassic, marine reptile approximately 1.5 metres (4.9 ft) long. It was elongated for hydrodynamic streamlining, with comparatively short limbs and a powerful tail. It would have been able to swim rapidly, by undulating its slender body in a snake-like fashion. It had only small limbs, which probably did not aid in swimming, and nostrils placed far back on the head, close to the eyes.

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.
