Edmontosaurus mummy SMF R 4036

The Edmontosaurus mummy SMF R 4036 is a dinosaur fossil in the collection of the Senckenberg Museum in Frankfurt, Germany. It was found in 1910 in Wyoming, United States, in rocks of the Lance Formation that are about 66 million years old. The mummy is ascribed to the species Edmontosaurus annectens. It comprises a nearly complete skeleton found wrapped in skin impressions, a rare case of preservation for which the term dinosaur mummy has been used. It is assumed that the individual died during a drought and the carcass dried out before being carried away by a sudden flood and buried rapidly. Sand filled the body cavity, preserving the three-dimensional shape of the body, and a biofilm on the skin formed a thin crust of clay that preserved the shape of the skin in positive relief (protruding up from the surface). The mummy was found by Charles Sternberg and his sons. It is one of the best-preserved hadrosaurid mummies and the second to be discovered. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
