Between researchers out in the field constantly looking for that next uncovered things and all the people using google to discover all kinds of things from the comfort of their computer chair, there might not be an end to all the things left to be uncovered.
At least 35 small pyramids, along with graves, have been discovered clustered closely together at a site called Sedeinga in Sudan.
Discovered between 2009 and 2012, researchers are surprised at how densely the pyramids are concentrated. In one field season alone, in 2011, the research team discovered 13 pyramids packed into roughly 5,381 square feet.
