An archeological dig on a small island in the English Channel uncovered a  rather perplexing piece of the past buried in a 14th-century grave: the  body of a porpoise.

The creature's bones were discovered after researchers stumbled upon a  well-crafted burial plot on the island of Chapelle Dom Hue, which was  once a retreat for monks.

Assuming that the grave contained a human being, due to the nature of  its construction, archeologists excavated the site and were stunned to  find the remains of the marine animal which was apparently buried during  medieval times. 

The discovery has left experts scratching their heads as to why exactly  the creature would have received such a strange send off.
