Discovery Channel’s popular show “Expedition Unknown” was recently on site to document the discovery of 12 human skeletons and artifacts dating back at least 2,000 years, which had all been long hidden beneath the famed Khazneh (or “Treasury”) in Petra. The colossal find was accomplished by a team lead by archaeologist Pearce Paul Creasman.

Despite its fame, an archaeological dig conducted by American and Jordanian researchers uncovered a hidden tomb featuring 12 human skeletons.
