Monstrous Crocodile Skeleton - Steneosaurus bollensis - 13.45 feet

Inventory quantity available: 1

This gigantic, well-articulated crocodile skeleton is a breathtaking find from the Holzmaden Shale near Stuttgart, Germany, a fossil locale renowned for its exceptionally preserved specimens.

This marine predator once inhabited warm Jurassic seas, which teemed with a variety of ammonites, ichthyosaurs, plesiosaurs, crinoids (sea lilies) and many fish species. It predates Tyrannosaurus rex by over 100 million years. 

In addition to its jaw-dropping size, the preservation is tremendous. For example, tracheal rings, skin impressions and all teeth are present in this dramatic, three-dimensional specimen. 

Considerable time and skill was needed to reveal this specimen from the surrounding matrix - meticulous, specialized work using the latest techniques and equipment. The preparation was carried out to the most exacting of standards, bringing to life every detail while preserving the integrity of the fossil.
