Such was the case, recently, when after two years of intensive work, archaeologists announced the discovery of a 7000 year-old Native burial site off the coast of Florida. Or, similarly, when archaeologists revealed new theories about the workings of the ancient Roman Plutonium, where animal sacrifices were made to reinforce notions of divinity. Or in Sweden, recently, when archaeologists discovered 8000 year-old human heads impaled on spikes.
