Evolution of the Vertebrates
In this course, we will explore the history of vertebrates revealed by fossils and living animals. We will cover the evolution of the major vertebrate groups, including discussions of the biogeography, stratigraphy, and paleoecology of select clades. Classroom activities will include hands on projects involving fossils, casts, and skeletons.
Topics to be covered:
- What are the major vertebrate groups today and in the past?
- When did major vertebrate groups evolve?
- How did vertebrate diversity change through time?
- Mass extinctions
- Major radiations
- What were some of the key innovations during the history of the vertebrates?
- The invasion of the land
- The evolution of flight
- Secondarily aquatic and marine vertebrates
Other topics include:
- Science and the scientific method
- Geologic time
- Paleontological techniques
- Human evolution
- Phylogeny estimation
- Behavior reconstruction
- Careers in the biosciences
This class will also include a field trip to the Gray Fossil Site, a 7-4.5 million year old fossil deposit found in 2001. The site is particularly well-known for its mammal fossils, but other vertebrate groups known from the locality include fish, amphibians, and reptiles. We will be visiting the associated museum, the fossil preparation and curation laboratories, and the site itself.
The criteria for assigning grades for the course are the following:
- Completion of in-class laboratory assignments.
- Class participation, including leading discussion on reading assignments.
- Preparation of a poster/presentation (team-based).
Passing grade for the course: C
Credit Hours: 3
My research interests center on vertebrate taphonomy, ichnology, paleopathology, and paleoecology. In particular, I study bone surface modifications generated under modern and experimental conditions to better understand the processes which left similar traces on bone in the fossil record. My current research projects include:
- testing methods for applying these modern analogies in a deep time perspective
- interpreting trophic interactions, behavior, and diet from bite marks left by different archosaurian groups, especially members of Crocodyliformes
- identifying and differentiating historically understudied traces and pathologies, such as bite marks vs. shell disease and different types of plant mediated damage to bone.
My name is Maggie and I am a first-year Ph.D. student studying the evolutionary and geochemical relationships of echinoderms (sea stars and sea urchins). Basically, I want to understand how echinoderms are related to each other and how they grow and interact with their environments and I do that by looking at fossils and the chemistry of modern echinoderm skeletons. In my free time I like to go kayaking, work in my garden, and hang out with my cat. This is my second year as a TA for Governor’s School and I am very excited to get to know you!
