This is quite an interesting article I found on discovery, so I thought I would share it. Archaeologists have uncovered a graveyard for what they believe to be Roman Gladiators. Their reasons for believing them to be Gladiators are that many of the skeletons were decapitated, the head was buried alongside the body, not where it should be, some of them have bite marks and lacerations and they were all buried respectfully in individual graves. They uncovered a total of 80 skeletons that have been dated to somewhere in the first century C.E.
Anyway, here's the link.
