Abstract
The Glen Dean/Bangor is a massive, cross-bedded skeletal calcarenite that is locally oolitic; it contains a sparse, thick-shelled fauna dominated by straparollid gastropods and the stemless crinoid Agassizocrinus. The lower part of the Pennington intertongues with the Glen Dean/Bangor and consists primarily of dark shale with interbedded calcarenite lenses; it contains a diverse fauna with many delicate, benthic forms. Most of the fauna is associated with the calcarenite lenses. The distribution of various echinoderm types relative to substrate is described. The Glen Dean/Bangor is interpreted to represent a high-energy carbonate sand belt of migrating shoals. Overlying parts of the lower Pennington are interpreted to represent deeper, protected lagoonal conditions leeward of the sand belt. from Authors
