The video in this episode of Shelf Life explores the Museum’s fossil collection of tiny marine organisms known as foraminifera or—when even scientists admit six syllables is a mouthful—forams. These are abundant, widely-scattered, single-celled creatures that still fill oceans today. The fossilized shells left behind by their foram forefathers are widely used as time capsules for ancient Foraminifera, Fossil Resource Information The concept Foraminifera, Fossil represents the subject, aboutness, idea or notion of resources found in University of Missouri-Kansas City Libraries . The Fusulinida is an extinct order within the Foraminifera in which the tests are composed of secreted hyaline calcite. Like all forams, they were single-celled organisms.

(PRI 49886) by Digital Atlas of Ancient Life on Sketchfab Numerous specimens of the fusulinid foraminiferan Fusulina sp. from the Pennsylvanian Graham Fm. of Coleman County, Texas (PRI 49886). Foraminifera (forams for short) are single-celled organisms (protists) with shells or tests (a technical term for internal shells).

Over time, each of these groups has evolved many different forms, including large complex tests associated with reefs. These groups of large The earliest known calcareous-walled foraminifera are the Fusulinids, which appear in the fossil record during the Llandoverian epoch of the early Silurian. The earliest of these were microscopic, planispirally coiled, and evolute; later forms evolved a diversity of shapes including lenticular, globular, and perhaps most famously, elongated rice-shaped forms. They get their name from the foramen, an opening or tube that interconnects all the chambers of the test. Fossilised tests are found in sediments as old as the earliest Cambrian (about 545 million years ago) and foraminifera can still be found in abundance today, living in marine and brackish waters. Microscopic, single-celled organisms called foraminifera have a fossil record that extends from today to more than 500 million years ago.

Foraminifera have a geological range from the earliest Cambrian to the present day. The earliest forms which appear in the fossil record (the allogromiine) have organic test walls or are simple agglutinated tubes. The term "agglutinated" refers to the tests formed from foreign particles "glued" together with a variety of cements.

In the fossil record an assemblage of benthic foraminifera may lead to an understanding of the ancient habitat. Benthic foraminiferal species show a wide range

Foraminifera are considered an order (sometimes a class) in paleontology, subdivided by the structure and composition of modern and fossil tests. They are ranked among the “Granuloreticulosa” in biology, characterized by (1) their branching and anastomosing networks of 2017-04-30 The oldest fossil foraminifera, from the Cambrian, are simple agglutinated tubes.
