T ENV 175Z  Physical/Chemical Analyses of Ancient Environments (4)
Chemical/physical data derived from early Jurassic sedimentary rocks containing abundant dinosaur footprints (i.e., evidence for a rich ecosystem) will be used to develop multidisciplinary constraints on the nature of the environments that existed about 200 million years ago. Students also collect data bearing on the mechanical and behavioral aspects of theropod dinosaurs that thrived in those environments. Two field trips to geological localities in Massachusetts and Connecticut occur during the semester to collect data that provide the basis for two, original 12-page papers written in a scholarly format. Formerly A ENV 175H. Open to Honors College students only. May not be offered in 2009-2010.
