The aim of palaeontology is the study of the historical dimension of life on Earth. This involves two facets fully related to the activity of the Institute: biodiversity through time, with its dynamics, and everything related to evolutionary patterns and rhythms. Both are highly interdependent. The biota has changed over time, both internally, as a result of evolutionary processes that modify the relationships between species to introduce new ones, as in regard to the modification of the physical environment, more than once produced by the own biological dynamics, but also by the internal activity of the Earth itself or changes in astronomical order. Therefore, in connection with this, we are interested in paleoecological and palaeobiogeographic aspects. The need for a correct reading of the data from the fossil record makes us to care for their formation and dynamics, ie, everything related to the field of taphonomy. While life has continued to the present, our research also covered the living present. Stratigraphic Paleontology investigates the fossils’ position in geological time and allows you to sort the various lithological units based on their fossil record (Biostratigraphy).
