Paleobotany and Palynology
Provide basic training with a view to characterizing the general aspects of plant evolution throughout Earth''''s history and its importance for stratigraphy and for the reconstitution and knowledge of past environments and climates.
They also include the characterization of objects of study in palynology (dinoflagellate cysts, spores, pollens) and aspects related to the applied use of these groups of fossils in chronostratigraphy and in the reconstitution of past environments and climates are developed.
Develop knowledge on Portuguese Paleobotany and Palynology, considering the most representative stratigraphic intervals;
Highlight the scientific, didactic and historical importance of fossils of plant macro-remnants and palynomorphs.

The teaching, supported in the use of multimedia projections, will include theoretical and practical classes.
In practical classes students will learn the laboratory procedure with the treatment of samples for research of dinoflagellate cysts, spores and pollens, obtaining palynological residues, preparation of thin slides and observation under an optical microscope for palynological analysis; palynofacies, identification of some forms.
Observation of collections of plant macro-remnants representing the evolution of vegetation over time.
The assessment will have a continuous component, through the completion of a written report, presented in PPT, followed by discussion.
The assessment consists of 2 fundamental elements: practical periodic assessment (weekly report on the study group) and systematic final work:
• The periodic practical assessment consists of a portfolio with systematic records of one of the specimens studied in each class (at your choice), which includes systematic framing, morphological description, taphonomy, stratigraphic and geographic distributions and paleoecology. They will be quoted from 5 values of the final grade.
• Presentation of a report (PPT) on 6 January. It will be quoted from 0 to 10 values (PPT) and 5 values (orality).
The final grade of the UC is obtained through the sum of the partial results of the evaluations, making rounding only in the final grade. It will be approved with a minimum classification of 9,5 values.
