A construction project in Grahamstown, South Africa has turned up a collection of fossils dating back 360 million years, some of which represent previously unknown species. The South African National Roads Agency, who was overseeing the construction, made the announcement in June 2016 after the fossils had been carefully excavated from other rock which was being cut with explosives.
