Story: Fossils

Fossil foraminifera

Fossil foraminifera

These photographs were taken with an electron microscope, and 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.
