Objective:

Micropaleontology is concerned with microfossils and nanofossils (the latter being smaller than 50 m), the study of which must, of necessity, be carried out using the light or electron microscope. To achieve this course, the microfossils* must be studied in terms of morphology, structure, chemical and mineralogical composition and taxonomy to discover their origin and systematic affinities. Application of these microfossils in the fields of oil-exploration, biostratigraphy, palaeo-biology and paleoclimatology is essential. This course emphasizes, in particular, on the microfossils that lived in or under the sea water. Thus, their interaction with the present-day physical, chemical and biological characteristics of the ocean water will be also addressed.

 

*Microfossils are the remains of unicellular, multicellular micro-organisms and the dissociated  

elements and skeletal fragments of macro-organisms. They consist of these  types: Foraminifera, Ostracods, Coccolithophora, Diatoms, Radiolaria and Dinoflagellates.
