Description
Color enhanced scanning electron micrograph (SEM) of the shell (test) of a Globigerina sp. planktonic foraminiferan. Foraminifera are marine single-celled protozoa that construct and inhabit shells composed of several chambers. These are usually penetrated by pores through which the cellular content is extruded. The shells form an important component of chalk. In past geological ages, foraminifera were so numerous that their shells, largely composed of calcium carbonate, have formed immense fossil deposits, seen today as limestone. This species is known from the Jurassic period onwards. Magnification x110 when printed at 10cm wide.
