Tschadbecken
In 1989, German scientists were working in northeastern Nigeria's Chad Basin as part of a cooperative project between the University of Maiduguri located in Borno State, Nigeria, and archaeologists of Goethe University Frankfurt. This project examined the beginnings of sedentary farming societies in the Chad Basin. Questions arose about whether there were other societies like those in the Chad Basin, and these questions led the team to investigate the Nok Culture. In the early steps of the Frankfurt Nok Project, researchers had difficulty finding sites to excavate. The team began collaborating with Umaru Yusuf Potiskum and they started finding distinct Nok culture sites, although most were looted. A few sites, however, were still intact, and artefacts found at these sites are described below.
