GSCI 101: Geological History of Life
This course is an introduction to the development and history of life on earth. Stress will be placed on understanding the environments of the changing earth, evolutionary processes, the fossil record, and the procedures used in scientific analyses.
GSCI 105: Environmental Science
The purpose of the course is to offer an introduction to the environmental sciences, a critical area of concern for all people, and an area of interest to many students. The objectives of a natural science core class in environmental science are to provide a course that is both comprehensive in its scope as a general review in the environmental sciences, as well as to introduce a mechanism for students to learn more about the environment, and to contribute in the future as environmentally aware and active citizens.
GSCI 351: Stratigraphy
This course is designed to provide an introduction to stratigraphic concepts, principles, processes, and techniques. Stress will be placed on recognition of sedimentary rocks, facies, and sequences to interpret stratigraphic relationships and sedimentary basin history.
GSCI 361: Invertebrate Paleontology
Taxonomy and morphology of major groups of invertebrate fossils. Topics include fossil invertebrate classification, evolution, taphonomy, biostratigraphy, paleoecology, and paleobiogeography. (Required field trips conducted outside of class hours.) Prerequisites: GSCI 112 or permission of instructor. Offered every fall
