Fossilised foraminiferans, SEM

Fossilised foraminiferans. Coloured scanning electron micrograph (SEM) of the fossilised shells of assorted foraminiferan protozoa (order Foraminifera). These calcium-rich shells were constructed by single-celled marine animals. The shells contain pores through which the animals extended branching pseudopodia, in order to catch particles of food. Foraminiferan deposits are the main constituent of chalk (limestone). They are important zonal fossils, being used to define the units of rock in which they are preserved.

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate beauty of fossilized foraminiferans, a group of single-celled marine animals that constructed calcium-rich shells. The colored scanning electron micrograph (SEM) reveals an assortment of these ancient shells belonging to the order Foraminifera. Foraminiferan protozoa developed porous shells through which they extended branching pseudopodia, specialized structures used to capture particles of food in their aquatic environment. These remarkable deposits are primarily composed of chalk, a type of limestone formed by accumulated foraminiferan remains over millions of years. The significance of foraminiferans extends beyond their role in rock formation; they also serve as crucial zonal fossils, aiding scientists in defining different geological units within preserved rocks. With a magnification level at x225 and measuring 6x7cm in size, this SEM image offers viewers an up-close look at the intricate details and delicate structure found within these tiny organisms. As we gaze upon this mesmerizing photograph, we are reminded not only of the incredible diversity and complexity present in nature but also how it has been shaped by countless generations before us. This snapshot into Earth's ancient past invites us to appreciate the wonders hidden beneath our feet and marvel at the rich history encapsulated within each fossilized shell.
