Foraminifera classification

It appears that these features correspond better to the main evolutionary trends in Foraminifera than wall composition and structure, both used in traditional classification. Foraminifera (or forams, for short), a kind of ubiquitous ocean dwelling organisms, are widely used in oceanographic and geoscience research. They are the most widely used fossil organisms for biostratigraphy, age-dating and correlation of sediments, and paleoenvironmental interpretation [1]. While 2013-04-01 · The classification of Foraminifera has a long history going back to the beginning of the 19th century and the work of d'Orbigny (1826) who established the order Foraminifera and proposed the first taxonomic system based on the growth plan of foraminiferal tests. d'Orbigny's successors have developed diverse systems based on the morphology of fossil and recent tests, differing principally by 2018-08-28 · Of the ~ 99,000 classifications provided, more than 61,000 are complete or damaged planktonic foraminifera. Objects also include benthic foraminifera, ostracods, pteropods, spicules, and In this book, evolutionary classification and nomenclature in the Cretaceous planktic foraminifera with at least one stage with chambers alternately added with respect to the test growth axis are analysed in seven articles.

The taxonomy is for more than 99% of the species based on the morphology of the test.

Foraminiferan shells, or tests, are built of hollow chambers separated by partitions, with small openings called foramina that connect the chambers (they get their name from these foramina).The final chamber (the last one added) has an opening or openings to the exterior, called the aperture.The living organism fills all the chambers in its shell except for Foraminifera.

Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Cassidulina is a genus of foraminifera described in the Treatise Part C. (Loeblich & Tappan, 1964), as having a free, lenticular test, with central boss of clear calcite on either side. Chambers are biserially arranged, enrolled planispirally with a subangular to keeled periphery.
