About the Course
Paleontology: Ancient Marine Reptiles is a four-lesson course teaching a comprehensive overview of the evolutionary changes that occur when air-breathing terrestrial animals return to water.
This course examines the diversity, adaptations, convergence, and phylogenetic relationships of extinct marine reptiles. Time Commitment: 3-5 hours per week
Students will explore three major groups of marine reptiles:
- ichthyosaurs,
- plesiosaurs, and
- mosasaurs.

Instructor
Michael Caldwell, Professor and Chair
Department of Biological Sciences, University of Alberta
Michael Caldwell's research is in the area of vertebrate paleontology, i.e., morphology, phylogeny, evolution, and ecology, etc. Organisms of interest include fossil and living squamates (snakes and lizards) as well as of extinct marine reptiles such as ichthyosaurs and plesiosaurs.
Current research is focused on marine and terrestrial snakes from Cretaceous rocks in the southern hemisphere (Gondwana), the cranial anatomy and phylogeny of extant scolecophidian snakes (blind, burrowing snakes), fossil mosasauroids from Upper Cretaceous rocks in New Zealand, Europe, Africa and North America, terrestrial lizards from the Cretaceous rocks of North America, and the molecular genetics of axial elongation in limb-reduced to limbless tetrapods.
