5.7" Horseshoe Crab (Mesolimulus) Fossil - Solnhofen Limestone

This is a rare fossil horseshoe crab (Mesolimulus walchi) from the famous Solnhofen Lagerstätte in Germany. It's good sized at 5.7" in length and preserved right side up on a large slab of limestone. There is one repaired crack running through the rock and the fossil. The fossil itself has some nice relief against the surrounding rock.

Comes with a display stand.

Mesolimulus is an extinct genus of arthropod. The best known examples are found in Solnhofen limestone near Solnhofen, Bavaria, Germany. Originally assigned to the living genus Limulus, they are related to and look virtually identical to the modern horseshoe crab. Other species assigned to Mesolimulus have been recorded from Spain, Siberia and (questionably) from Lebanon. Horseshoe crabs in general date to the Ordovician Period, more than 440 million years ago, and late Paleozoic Euproops fossils indicate that they have changed little over the last 300 million years.

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.
