Archaeologists excavating a suburb of Pompeii made a stunning discovery: the petrified remains of a harnessed horse and its saddle. The incredibly intact artifacts were found on the grounds of a villa belonging to a high-ranking military officer, according to the Associated Press. Experts said the horse was likely killed by volcanic ash or boiling vapors when Mount Vesuvius erupted in 79 A.D., destroying Pompeii and surrounding areas. Pompeii archaeological park head Massimo Osanna said officials hope to open the villa to the public at some point.
