Sustainable Development Goals

Learning Goals

Promote specialized skills in Invertebrate Paleontology, including morphology, classification, evolution and phylogeny,
biostratigraphy and palaeoecology of taxonomic groups of the fossil record;
Develop knowledge on Portuguese Paleontology, considering the fossil sites and stratigraphic intervals;
Reveal the scientific, didactic and historical importance of fossil invertebrates.
Students will have to develop skills related with:
Morphologic individualization, scientific drawing and taxonomic classification of fossil invertebrates;
Establishment of biunivocal correspondences between fossil invertebrate associations and the order and relative age of
stratigraphic units;
Use of taxonomic uniformitarianism and functional morphology criteria applied to the characterization of palaeoenvironmens, ecological requirements and ways of life of palaeospecies;
Identification of Portuguese fossil sites and evaluation of their importance in the palaeogeographic evolution of the country.

Teaching Methods

The programmatic contents will be taught through expositive theoretical lessons and practical lessons in the laboratorial
handling of collections of specimens. These activities will be complemented with one or more field and/or museum classes.

The evaluation will be completed through a general test (theoretic-practical and theoretic contents), together with a portfolio (theoretic annotations and practical exercises) and individual work of research.
