Ocean bottom currents and their effect on Ordovician Fauna, draft #1.

This article submitted by Sarah Beasley, Pete Rivizzigno, Jim Foley on 9/23/97.

In our study we shall examine slabs of Ordovician sediment and the orentianion of the species on them. In our study we hope to determine the relative set and drift of the Ordovician ocean currents and their role in shaping ocean floor life. We expect slower currents to reveal smaller species with a concave orientation, and with a greater abundance of species. In faster currents we expect to see larger species with a convex orientation and a lower species density. We think that we will find this because faster currents will carry and distribute more, leaving a lower density of species. We plan to collect an undetermined amount of slabs from the arnheim, waynesville, liberty and whitewater formations. On each slab we will determine the orientation of the fossils (angle, direction, position), and the number of species in a controlled specified area on each slab. Problems might arise in finding undisturbed slabs of sediment. We hope to find methods that will help us minimize this problem.
