OVERVIEW

Paleobiology is the science that seeks to reconstruct the biological aspects of organisms that are now extinct and uses methods that straddle earth sciences and biological sciences to study the life of organisms in past eras. Paleobiology therefore has the great merit of being able to access large data of populations over very long time intervals and therefore be able to test questions inherent to evolution, adaptation and paleoecological variations by moving freely along temporal and environmental gradients.

AIMS AND CONTENT

LEARNING OUTCOMES

The student will be able to approach the study of the biology of extinct organisms through the study of the functional morphology of preserved remains. The basis for the recognition of the living and depositional environments of individual taxa will be provided. The implementation of ichnological information will serve to reason about the ethology of fossil remains and thanks to paleoecological insights it will be possible to deepen essential aspects on the characterization of marine communities in environments of all depths.

AIMS AND LEARNING OUTCOMES

At the end of the course the student will be able to:

• use the correct methodology in the interpretation of the biological signal in past eras;
• know how to use the morphology of fossil remains in an applicative manner in order to reconstruct the paleoenvironment within which the community of organisms lived;
• recognize and discuss any variations with respect to the fossilization environment;
• correlate paleobiological and paleoecological aspects in a context of climate changes in the most remote but also very recent past eras;
• interpret the evolution of biodiversity in space and time knowing how to recognize the main factors that have led to modern conditions and try to reason about future biological and ecological scenarios.

PREREQUISITES

Notions of systematics of marine organisms, mastery of correct taxonomies for the morphological description of organisms.

TEACHING METHODS

The teaching consists in frontal classes, laboratories with fossil materials and practicals on the field.

Attendance at classes is strongly recommended, while attendance at practical and laboratory activities is mandatory at 75%.

The way lessons are taught may be modified due to emergencies that prevent in-person lessons from being held. In this case, classes will be held via the Teams platform using suitable substitute teaching tools.
