SOES3049 Vertebrate Palaeobiology: Phylogenetics and Evolution

Module Overview

To familiarise students with the basics of broad-scale vertebrate evolution.

Aims and Objectives

To familiarise students with the basics of broad-scale vertebrate evolution, encompassing fish, amphibians, reptiles (including archosaurs - dinosaurs, pterosaurs and birds) and mammals. This course will build on current understanding of the evolutionary (=phylogenetic) relationships of vertebrates and will develop recent research questions in, particularly, archosaur systematics, palaeobiology and marine fossil vertebrates. A theme of this course will be quantitative approaches to tree-building: phylogenetic methods and the analysis of character data (both morphological and molecular). Students will receive an overview of the vertebrate fossil record, current consensus on (and debates about) the interrelationships of living vertebrates and the theoretical and practical basis of phylogenetic analysis.

At the end of the module students will:

  • Understand the basic shape of vertbrate evolution and the kinds of data (fossils, morphology, molecules) used to hypothesise and quantify tree shapes;
  • Gain a broad knowledge of the fossil record of vertebrates, inherent biases and the interrelationships of the key lineages;
  • Understand how phylogenetic trees are constructed, tested and falsified and the problems inherent to the inclusion of fossil taxa;
  • Gain an understanding of the broad fossil record, anatomy and palaeobiology of the major lineages of fossil vertebrates, with emphasis on specific examples of marine vertebrates;
  • Understand how the fossil record of vertebrates has been instrumental in shaping current consensus on the relationships of living animals.

Key Skills Acquired:

  • Analysis of the fossil record and understanding of biases;
  • Phylogenetic approaches, character coding and quantitative tree-building;
  • Statistical analysis of character data (i.e., how to code a phylogenetic matrix);
  • Written communication / presentation skills;
  • Oral and visual presentation skills (esp. poster and seminar);
  • Information retrieval skills (library/web);
  • Report writing;
  • Teamwork.

Learning and Teaching

Study time allocation

Contact hours:60
Private study hours:90
Total study time: 150 hours

Teaching and learning methods

The basis of this course is a series of 24 lectures. Lectures will cover course material in a general way, and will provide numerous suggestions for further reading and student self-learning, in particular via pointers to the primary literature.

Resources and reading list

A small budget will be required for the costs of printing student posters.

Online lecture notes, presentation files and primary literature will be presented to students. Background reading and self-learning will be required.
