CONCLUSIONS
1. Energy levels of the during the deposition of
the Hughes Creek Shale were strong enough to
oscillate many of the fusulinids causing
corrasion. However, the energy in the water
(most likely due to depth) was at times minimal
allowing dead fusulinid tests to come to rest in
a preferred orientations. 2. This preferred
orientation of fusulinid tests allowed for 67 of
the epibionts to occupy the last half of the
final volution. The most likely orientation to
explain these results would be the fusulinid
tests coming to rest slightly submerged in the
clay-rich environment. This would greatly reduce
the substrate for encrusters of the
