Fossil diatoms. Coloured scanning electron micrograph (SEM) of fossilised diatoms, single- celled planktonic algae. The diatoms create a shell (frustule) of silica around themselves for protection and support, which is readily fossilised. These diatoms are from the Miocene epoch, around 23 to 5 million years ago. These diatoms were found in Maryland, USA.
