didnt see a thread on this http://www.livescience.com/26903-35-ancient-pyramids-sudan.html Among the discoveries are pyramids with a circle built inside them, cross-braces connecting the circle to the corners of the pyramid. Outside of Sedeinga only one pyramid is known to have been built in this way.

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 (500 square meters), or slightly larger than an NBA basketball court. They date back around 2,000 years to a time when a kingdom named Kush flourished in Sudan. Kush shared a border with Egypt and, later on, the Roman Empire. The desire of the kingdom's people to build pyramids was apparently influenced by Egyptian funerary architecture.
