Fossil foraminifera have been found in rocks as old as 500 million years, and it is highly likely they lived even further back. The Burke Museum has a large collection of fossil forams from West Coast marine sedimentary rocks. What can this tell us about Puget Sound?

It was found at Pago Beach on the island of Guam. Image is magnified 40 times under a microscope which should equate to a 1 mm field of view.

Foraminifera (‘hole bearers’), foraminifers or forams for short, are a large phylum of amoeboid protozoans (single celled) with reticulating pseudopods, fine strands of cytoplasm that branch and merge to form a dynamic net.

The most important factors that control living foraminifera are salinity and temperature, but other things like the substrate (weed, rock, silt, mud, sand, etc), the amount of light, and the amount of oxygen dissolved in the water are important. The oldest known fossil foraminifera are agglutinated tubes three or four centimetres long. These were the first textulariids, a group of foraminifera still found living today, 570 million years after they first evolved.

Foraminifera (forams for short) are single-celled organisms (protists) with shells or tests (a technical term for internal shells). They are abundant as fossils for the last 540 million years. The shells are commonly divided into chambers that are added during growth, though the simplest forms are open tubes or hollow spheres. One of these groups, the planktonic foraminifera, has a rich fossil record that has been vital to our understanding of the history of Earth’s oceans and climate. The name “foraminifera” is derived from the Latin word foramen, which means ‘opening’, referring to the apertures in their shells, or tests.
