Concretions are found near and far, from Western Kazakhstan to beaches in California. Usually the size of cannonballs, they form from water eroding a piece out of sedimentary rock. They almost look man-made.

Geologists reassessed the abundance of fossils in Earth’s uppermost rock layers this year, and they believe they found a remarkable sixth global extinction event.¹ Their discovery has two significant implications.
