EAS 1700 Worksheet 03 Y OUR N AME ……………………………………… E XERCISE 1: R ECONSTRUCTING N EW Y ORK S P ALEOZOIC P ALEOTOPOGRAPHY (25 points) Using the Cambrian through Silurian and Devonian correlation charts and the elevation- measuring scheme in Table 1, plot paleotopographic profiles for each fossil-defined time interval (biostratigraphic zone), using your judgment to creatively time-average the elevation scores for each zone × longitude box. (25 panels @ 1 point/panel = 25 points) E XERCISE 2: T ESTING AND I NTERPRETING THE R ECONSTRUCTION (25 points) Time-correlation by volcanic ash layers reveals that the Amorphognathus superbus (A.s.) Zone overlaps in time with the Triarthrus becki (T.b.) Zone, higher A.s.-Zone limestones grading eastward into T.b.-Zone black shales. Paleocurrent directions from these strata (MO ) appear in the 74˚30'-76˚30' W longitude interval. 1. Going by the paleocurrent evidence alone, was the black shale deposited in shallower or deeper water than the limestone?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
