Vertebrate Geobiology is the application of biological principles and fossils to the study of earth history. This course covers vertebrate morphology, phylogeny, taxonomy, evolution, biomechanics, biogeography, and paleoenvironments, and stratigraphic history, with lab practicals that focus on osteology, functional interpretation, phylogenetic reconstruction, functional morphometrics, scanning, and analysis of data sets.
