Learning outcomes

The course will focus on marine macrobenthic fossils to link stratigraphic and paleobiologic patterns and processes. The distribution of taxa in time and space is controlled not only by ecological and evolutionary processes (e.g., taxa environmental niches, extinctions/originations), but also by sedimentary processes that govern where and when fossil-containing sediments are deposited and preserved. Stratigraphic, taphonomic and ecologic attributes of fossil assemblages can be potentially useful for detecting biological trends, environmental shifts and climate variability through time and space, correcting stratigraphic biases that affect the fossil record, or enhance sequence stratigraphic interpretations.

Course contents

  • Introduction to Stratigraphic Paleoecology.

  • The nature of a sample and the stratigraphic framework.

  • Environmental controls on the distribution of species.

  • Stratigraphic controls on fossil occurrences.

  • Paleoecology, biodiversity, ecosystem change through time.

  • Field trips and paleoecologic inferences directly in the field.

  • Quaternary climate changes and implications for the marine fossil record: Case studies.
  • Mollusk key-taxa for paleoenvironmental inferences.
