Figure 2 — The fossil Eosphaera tyleri from the Gunflint chert, Ontario, Canada. The top panel shows the fossil using conventional microscopy. The images below show a 3D reconstruction of this complex fossil, which consists of two large spheres and a number of smaller ones. Scale bars are 10 micrometres. Modified from Brasier et al.
