These photographs taken with an electron microscope show in remarkable detail the surface of three fossil foraminifers found in sediment. The two ball-like clusters are minute plankton that lived at the ocean surface. The flatter shell is a form that lived on the sea floor. When they die, the shells of plankton build up on the seabed and eventually form rocks such as limestone.
