Paleontology and Stratigraphic Geology

A.Y. 2021/2022
Overall hours
GEO/01 GEO/02
Learning objectives
Recognize and understand the processes leading to the formation of the sedimentary rocks. Leran the principles of stratigraphy. Understand the processes leading to the production of the fossil record. Encourage learning about the main groups of invertebrates commonly used in paleontology, also considering dissemination asa possible goal.
Expected learning outcomes
Capacity to recognize the main groups of sedimentary rocks and to apply the principles of stratigraphy. Capacity to recognize the transition of organic remains from the biosphere to the lithosphere. Acquisition of expertise about the main groups of animals whose fossil record contributes to the knowledge about biological evolution. Ability to disseminate the acquired knowledge on sedimentary processes and fossilization.
Course syllabus and organization

Single session

Lesson period
First semester
In case of emergency (Covid-19).
Teaching methods:
Asynchronous lessons (videolessons recorded by the professor with audio commentary) will be made available, organized to cover the topics of each week according to the established timetable.
Some of the lessons will be used as a moment of revision and deepening of what is proposed in the asynchronous lessons, and will be carried out using the Microsoft Teams platform.
All the above material, the pdf of the slides and notices relating to any update related to the evolution of the legislation imposed by Covid-19, will be timely published on the Ariel website of the course.

The program and reference material will not change.

Learning assessment procedures and criteria:
The exam will be held orally using the Microsoft Teams platform. In particular, the exam will be aimed at:
- ascertain the achievement of the objectives in terms of knowledge and understanding;
- ascertain the ability to apply knowledge and understanding and the autonomy of judgment through the discussion of case studies discussed during the lessons;
- ascertain the knowlwdge of the specific terminology and the ability to present the arguments in a clear and orderly manner.
Course syllabus
Stratigraphic geology
Rocks and petrogenetic processes
Classification and properties of sedimentary rocks
Processes of formation of sedimentary rocks
Terrigenous rocks
Carbonate rocks
Other types of sedimentary rocks
Stratification and sedimentary structures
Principles of stratigraphy
Stratigraphic units
Stratigraphic relationships

Taphonomy: from the biosphere to the lithosphere.
The species in Paleontology: definition and problems.
Biostratinomy: from the causes of death to the burial of an organism through the physical- (bio) chemical processes that can affect its morphology and preservation.
Fossilization s.s. (fossil-diagenesis): description of the chemical-physical processes that affect the composition and structure of the organic remains in a sediment / rock. Burial conditions. Diagenesis of non-mineralized tissues. Formation of autigenous minerals in association with non-mineralized tissues. Preservation / alteration of biominerals. Types of fossils.
Fossil deposits (Fossil-Lagerstätten).
Trace fossils: systematic and interpretation in terms of biological activity

The main groups of invertebrate fossils
Main characteristics of: cnidarians, brachiopods, bivalves, cephalopods, trilobites, echinoderms. Notes on the importance of individual groups in the field of Earth Sciences.
