Duckbilled dinosaur

The virtually complete original skeleton of the Edmontosaurus in the Senckenberg Nature Museum in Frankfurt counts among the most important dinosaur fossils in the world. In this specimen, even the structure of the skin has been preserved as a fossilized imprint. Worldwide, there are only fewEdmontosaurus specimen that show this high level of preservation. The animal’s apparently cramped posture suggests that this dinosaur had already been mummified before the body was covered by sandy sediments. This allowed the hardened skin to imprint in the sediment and be preserved as a fossilized impression.
