Lithology and environment

Includes fossils?Y
Lithology description: This bryozoan rich community is associated with light to medium gray, calcareous mudstones. Associated lithologies include calcisiltites and lenticular calcarenites, rarely displaying upward fining, mudsheltering (matrix trapped in protected pockets beneath shells during winnowing) and/or starved ripple features. Brett (1983) considered that these coquinoid beds represent winnowed storm layers and suggested deposition within storm wave base.
