چکیده :

Calcareous nannofossils include the coccoliths and coccospheres of haptophyte algae and the associated nannoliths which are of unknown provenance. The organism which creates the coccosphere is called a coccolithophore, they are phytoplankton (autotrophs that contain chloroplasts and photosynthesise). Their calcareous skeletons are found in marine deposits often in vast numbers, sometimes making up the major component of a particular rock, such as the chalk of England. One freshwater species has been reported. Formally coccolithophores are separated from other phytoplankton such as diatoms by the presence of a third flagella-like appendage called a haptonema, although the flagella bearing stage is often only one of a multi-stage life cycle. In this article introduce software that TSC is a wide range of applications, Calcareous Nannofossils during the Mesozoic and Cenozoic drawing is displayed. Software calendar geological stratigraphy and paleontology science researchers suggested.
