Learning objectives
Acquisire le metodologie micropaleontologiche (tafonomia, sistematica, biostratigrafia, paleoecologia) dei principali gruppi di microfossili. Applicazioni dei metodi a: datazioni relative delle rocce sedimentarie, analisi delle facies marine profonde e costiere, e ricostruzioni ambientali, climatiche ed oceanografiche del passato.

Syllabus
The micropaleontology applied to stratigrafic researches and paleoenvironmental, paleogeographical and paleoceanographical reconstructions. Practical use of micropaleontology in petroleum research.
Foraminifera: biology, morphological characters and principles of classification. Families and Genera of benthic habitat in sedimentary successions. Ecology and paleoecology of planktonic foraminifera: the main controlling chemico-physical parameters (turbidity, temperature, oxygenation, depth, latitudes, etc.), paleobathymetric and paleoceanograhic recostructions. Stratigraphic distribution of benthic and planktonic and their biostratigraphic resolution.
Calcareous Nannofossils, Conodonts: biology, morphology, principles of classification, ecology and paleoecology and stratigraphic distribution.
Preparation techniques in laboratory: thin sections from hard rocks and smearslides of nannofossils for the study at the optical microscope; sediment washing for obtaining residues to study foraminifera and ostracods at the stereomicroscope. Analysis at the stereomicroscope: identification of organic and inorganic components in single slides and description of the washed residues. Picking of foraminifera from residues on the basis of their type of walls, identification of the main taxonomic characters of the picked specimens using practical keys, large-scale foraminiferal moulds, atlases, and Taxomorph software. Paleoenvironmental significance of a benthic foraminiferal assemblage.
Cretaceous to Recent planktonic foraminifera identification of marker species and of biozones on the basis of planktonic foraminiferal assemblage present in washed residues using atlases and distribution charts. Identification in thin sections of the main genera of larger foraminifera and their stratigraphic significances using atlases.
