M. 2004. Earth System History, 2nd Edition. W. H. Freeman & Company, New York. Laboratory manual: Groves, J. R. 2002. Laboratory exercises in Earth History. Individual chapters can be downloaded at: http://faculty.cns.uni.edu/~groves/ Objectives: The objectives of this course are: (1) to establish basic principles for interpreting ancient physical and biologic events; (2) to review evidence for the main physical and biologic events in Earth’s history; and (3) gain an appreciation for the interdependence among Earth’s physical and biologic systems over the past 4.6 billion years. Tests and Grading: Four 100-point lecture exams…………..………………………... Laboratory exercises and exams..………………………………. Term paper…………………………………………………………. Total 400 points 200 points 100 points 700 points Grades will be determined roughly as follows: 100–90% = A; 89-80% = B; 79–70% = C; 69–60% = D; 59% and lower = F. Favorable consideration will be made for students who attend class regularly, who demonstrate a positive attitude and who clearly possess a better understanding of the subject matter than might be reflected by their point total. Other info: Please, no food or drinks in classrooms or labs. Lecture and lab attendance is required. A full letter grade will be deducted for 5 or more unexcused absences. No make-up exams, unless student receives instructor’s prior consent. Students with disabilities may arrange for special accommodations by contacting Jane Slykhuis, Coordinator of Disability Services, UNI Counseling Center, in Rm 213 of the Student Services Center (273-2676). Course includes an optional Saturday field trip to Devonian Fossil Gorge or Rockford Fossil and Prairie Preserve. Participants will receive 10 bonus points. Participants on the Geological Society of Iowa field trip will also receive 10 bonus points! 1 Course outline: Date: Lecture topic: Lab Topic: Week 1 Jan 8-12 Chapter 1: Earth as a system Exercise 1: Rock review (10 pts) Week 2 Jan 15-19 Chapters 3 and 7: The diversity of life, evolution, and fossils Exercise 2: Relative and absolute dating (10 pts) Week 3 Jan 22-26 Chapter 5: Sedimentary environments Exercise 3: Siliciclastic sediments (10 pts) Week 4 Jan 29-Feb 2 Chapter 6: Correlation and dating Exam I (100 pts) Exercise 4: Facies relationships (10 pts) Week 5 Feb 5-9 Chapter 10: Major chemical cycles Exercise 5: Biostratigraphy (10 pts) Week 6 Feb 12-16 Chapter 11: The Archean Eon Exercise 6: Fossil preservation; trace fossils; stromatolites Week 7 Feb 19-23 Chapter 12: The Proterozoic Eon Exam II (100 pts) Exercise 7: Trilobites, graptolites archaeocyathids, nautiloids Week 8 Feb 26-Mar 2 Chapter 13: The early Paleozoic world Exercise 8: Sponges, bryozoans, brachiopods Week 9 Mar 5-9 Chapter 14: The middle Paleozoic world Fossil Identification Exam I (70 pts) Week 10 Mar 12-16 Spring Break Spring Break Week 11 Mar 19-23 Chapter 15: The late Paleozoic world Exam III (100 pts) Exercise 9: Rugose and tabulate corals; ammonoids; belemnites Week 12 Mar 26-30 Chapter 16: The early Mesozoic Era Exercise 10: Crinoids, blastoids, fusulinids, plants Week 13 Apr 2-6 Chapter 17: The Cretaceous world Exercise 11: Gastropods, bivalves, scleractinian corals Week 14 Apr 9-13 Chapter 18: The Paleogene world Fossil Identification Exam II (70 pts) Week 15 Apr 16-20 No class No class Week 16 Apr 23-27 Chapter 19: The Neogene world Exercise 12: Hominid evolution Week 17 Apr 30-May 4 Finals Week: Exam IV (100 pts) Wednesday, May 2, 10:00-11:50am 2 Term papers: The deadline for turning in term papers is Monday, April 9 at 5:00pm. Students may turn in a draft on or before March 26. Drafts will be edited, graded and returned to authors, who may then revise their papers and resubmit them for a higher grade. Papers should be 6–7 pages in length (1” margins on all sides; double-spaced; 12 point font). Illustrations are highly encouraged, but they will not count toward the minimum page limit. A well organized and concise 6-page paper will receive a better grade than a poorly written 7-page paper. No fluff please. Papers must be organized as follows. Deviation from these guidelines will result in an automatic 30 point deduction. __________________________ Title (16 point bold font; left-justified; upper and lower case) Author (12 point bold font; left-justified; upper and lower case) ABSTRACT (12 point bold font; left-justified; upper case) The abstract is a very short summary of the main conclusions of the paper. It is not an outline of paper. INTRODUCTION (12 point bold font; left-justified; upper case) The purpose of the introduction is to introduce the topic, establish the significance of the topic, and briefly review previous literature on the topic. Cite references as necessary: for example (Smith 1997). Internet sources are unacceptable. MAIN HEADING(S) (12 point bold font; left-justified; upper case) This is where you actually discuss your topic, including any illustrations that may be appropriate. Cite references as necessary: for example (Wilson 1975). Internet sources are unacceptable. Sub-heading(s) (12 point bold font; left-justified; upper and lower case) Although not required, you may use sub-headings to help organize information within a given major heading. REFERENCES CITED (12 point bold font; left-justified; upper case) You must list the references you cited within the introduction and main body of text. List references alphabetically according to authors’ last names. Use the following format: Smith, J. S., 1997. What I did on my summer vacation. Journal of Meaningless Stuff, 16:39-47. [an example of a journal article] Wilson, A. B., 1975. Volcanoes I have known and loved. Freeman Publishing Company, Chicago, 285 p. [an example of a book] Other stuff: Do not use the MLA format (this will result in point deductions). If you have questions about how to organize your paper, how to cite references, how to list references cited, or anything else, please contact the instructor. You are strongly encouraged to visit Rod Library and consult a recent issue of the journal Geology to see how your paper should be organized and formatted. 3 Term papers must be written on some aspect of Earth History. Papers whose main focus is meteorology, astronomy, anthropology, or any non-geologic field are not acceptable. You may not turn in a paper written for another class. Plagarism will result in 0 points for the paper and disciplinary action from the University Administration. The following are some ideas, but students may choose another topic with the instructor’s approval. Ice ages / continental glaciations Endosymbiont hypothesis Mineral resources Development of geologic time scale Radiometric dating Continental drift and biogeography Origin of life Precambrian fossils end-Cretaceous mass extinction end-Permian mass extinction Burgess Shale fauna Global warming / environmental change Origin and/or extinction of dinosaurs Catastrophism vs. Uniformitarianism Cladistics and phylogeny reconstruction Origin of coal Assembly and break-up of Pangaea Forensic geology Geophysics / seismic geology Evolution of atmospheric composition Asteroid impacts Recent geologic catastrophies Origin and extinction of mammals History of plate tectonics Geologic hoaxes, fakes, and pseudo-science Biography of a famous geologist Environmental geology of a selected area Geology and public policy Isotopes in geology Plant evolution Convergent evolution and iterative evolution Fossil preservation Paleomagnetism Depositional environments Stromatolites Paleoclimatology Snowball Earth Banded iron formations 4
