Lagrange Point

Infrastructure projects and large engineering projects can lead to archaeological discoveries. When you start digging a large sewer network, the last thing you suspect to find is 1,000s of fossils. Large water projects in Auckland managed to discover new species and shed light on New Zealand 3 million years ago. We often think of modern plumbing as being a sign of the modern era, but in ancient China, a community banded together to build their own drainage network.
