FORAMINIFERA - explained
What are ForaminiferaForaminifera, or forams for short, are single-celled organisms that live in the open ocean, along the coasts and in estuaries. They consist of cytoplasma, which is stabilized and protected by an inner shell called test. Either they float in the water column (planktonics) or live on the sea floor (benthics). Of the approximately 6,000 species living today, only about 50 species are planktonic. It is estimated that there are about 80.000 species, which went extinct.
The word ForaminiferaThe word is derived from the Latin words for opening "foramen" and to bear "ferre". So literaly foraminifera means opening bearing. Usually they have one major opening called aperture and miniature smaller ones. Some have secondary apertures. While openings are a mutual feature of all foraminifera, they play in taxonomy only a minor role. ... more on apertures
Where do Foraminifera live ?Foraminifera are abundant all over the oceans. A few species live in freshwater environments. Forams live in the deep sea, open waters, near shore and even in areas only partly covered by sea water. Each niche has a specific mixture of species, called fauna. Explore the foraminifera in todays oceans via the zoomable map of our finds or the database-query choosing an ocean, area and/or locality.
Benthic ForaminiferaThey live on the seafloor and adapt to the local habitat they live in. Major factors of such seafloor habitats are food supply, light, predators, water-depth, salinity, temperature and the given substrate. In the fossil record an assemblage of benthic foraminifera may lead to an understanding of the ancient habitat they lived in. Benthic foraminiferal species show a wide range of life styles and forms. ... to the images
Planktonic ForaminiferaThey drift in the oceans. Their habitat are open waters from the surface to several hundred meters below. Only about 50 species live in todays oceans, but the number of individuals is enormous. Wide areas of the ocean floors are covered by their remains, the so called test. These tests are a most common source of paleoceanographic and stratigraphical studies. Read more in this PDF written by Prof. Dr. M. Kucera, Bremen.... to the images
TaxonomyAs single celled organisms with a nucleus, foraminifera belong to the kingdom of protists. They build an own phylum with 80.000 described species. Though they digest organic matter they are no animals. The taxonomy is for more than 99% of the species based on the morphology of the test. The wall material of the test and the chamber arrangement are the most important features to describe benthic species. Consult our key to benthic species. For planktonics the test surface and chamber arrangement are important. Consult our key to planktonic species. Read more in this PDF by Dr. B.Granier, Brest.
Fossil Record of ForaminiferaThe chronostratigraphic range of foraminifera extends from the Early Cambrian till today. The first forms to appear had organic tests or were simple agglutinated tubes. In the Paleozoic Fusulinida played an important role with a rich variety of forms. In the Mesozoic an enormeous radiation of species took place of which many went extinct at the end of the Cretaceous. The Cenozoic saw again a huge radiation. In total 80.000 species are described and used in the biostratigraphic correlation of strata. ...explore the fossil record of foraminifera

THE FORAMINIFERA.EU PROJECT
A Citizen Science ProjectThe Foraminifera.eu Project (FEUPRO) is run by a team of avocational scientists, who gets great support by professionals and amateurs. We want to foster the interest in foraminifera as an important but mainly neglected form of life. Our freely accessible database is a major outcome. We work out of natural enthusiasm on a strictly non-commercial basis. ... read more
The Foraminifera.eu Database (FEUDAT)FEUDAT contains to date 15.000+ datasets each with an image and 30+ attached data. The data allow to build interfaces for users to search for foraminifera on a wide range of criteria. Besides of taxonomy criteria on morphology, geography, geological time, collection, type pf image, fauna, realibility of the identification are offered to choose from. The result is presented as a plate with up to 500 images. FEUDAT is freely accessible. Contributors may find their collection of foraminifera better accessible than ever. ... to the database
PROJECTS AND CATALOGUES
ProjectsWhenever contributors and we decide to work on a specific topic for a year or more a project is established. Our first project in 2009 was the building of our database. It is now part of our daily work. Then in 2010 we established the project '"Sternberger Gestein", a Oligocene glacial erratic. The Working group of Upper Cretaceous foraminifera is continuosly enlarging the according catalogue. Further projects are built on Portuguese Foraminifera, those from the Mauritanian Shelf and on forams in the Eocene Heiligenhafener Kieselgestein.
CataloguesA major outcome of the Foraminifera.eu Project is a catalogue with to date 15.000+ forams. It is mainly achieved by projects and focussed work on specific foraminifera. One of the goals of these specific studies is to build catalogues of the according foraminifera. Whenever a representative amount of species are documented a catalogue is established. The catalogues are described below.
Catalogue of Upper Cretaceous ForaminiferaThe Working group of Upper Cretaceous foraminifera has created over time a catalogue of 2500+ Upper Cretaceous Foraminifera. It started with own finds from Upper Campanian quarries near Hamburg and was soon substantially enlarged by contributions of images by professionals. The enlargement is ongoing and your contribution is welcome to enlarge the coverage. ... to the catalogue
Catalogue of Portuguese ForaminiferaThe Working group of Portuguese Foraminifera has created a catalogue of 800+ foraminifera from Portugal. The basis was 8 years of field work in the Algarve by Brian and Michael. Portuguese professionals contributed many SEM images. The catalogue comprises specimens from recent waters and fossil foraminifera from the Miocene, Cretaceous and Jurassic. ... to the catalogue

March 2020: Sandcollector Loes Moddermanfrom the Netherlands contributes a set of 34 images. It is common, that sandcollectors find forams in their beach sands. Waves role the shells over and over until they are gone. Beach sands may contain a mix of well preserved shells to heavily corroded pebble like objects. Loes has nicely illustrated this specific mix of forams, which sandcollectors frequently see and enjoy. If you haven't noticed the foraminifera yet, take a closer look into your beach sands. ... see more
March 2020: Michael Dietrich contributes imagesof foraminifera from sand of the creek Szejdlik near Stare, district Trebivlice in the Czech Republic. The sand is found by sandcollector P. Vodila. We think that the foraminifera indicate an Upper Cretaceous age. Amongst the genera are Neoflabellina, Ammobaculites, Lenticulina and Frondicularia
