Pennsylvanian Fossil Gallery - Foraminifera. Protozoa Fossil identification by Jo Cox unless otherwise noted Common Name: fusilinids or "rice fossil".

2013-10-01 · The foraminifera are a group of amoeboid heterotrophic protists which are common in plankton ecosystems throughout the world oceans. Planktic foraminifera produce elaborate skeletons of calcium carbonate that have constituted a major component of the microzooplankton fossil catalog since the early Jurassic (Hart et al., 2003).

Forams are tiny protists. Protists are not animals, plants, or fungi, but rather a distinct phylum of the eukaryote kingdom. Most foraminifera are marine, benthic (living on or near the seafloor) organisms. Foraminifera have a geological range from the earliest Cambrian to the present day.

However, due to the inadequate preservation of early unilocular (single-chambered) foraminiferal tests and difficulties in their identification, the evolution of early foraminifers is poorly understood. Formaninifera (forams for short) are micro-organisms use extensively in age dating and correlation of marine and brackish-water sediments, and in determining paleo-ecology. Forams produce shells, known as tests, that vary in form, composition, and internal complexity.

When they make their shells, they incorporate oxygen from the ocean, which contains both 16 O and 18 O, and as a result, scientists can use foraminifera shells to obtain delta-O-18 values and to determine the ocean temperature at the time of the shell's creation. 2013-10-01 · The foraminifera are a group of amoeboid heterotrophic protists which are common in plankton ecosystems throughout the world oceans.

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. 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.
