Figure F4. Summary showing stratigraphic distribution of bryozoan growth forms, Unit I. Each subunit is interpreted to form a package grading upward from bioclastic packstone at the base to bryozoan floatstone and rudstone at the top. The diversity of bryozoan growth forms is low in the lower packstone-dominated part and high in the upper floatstone-dominated part. The growth of the bryozoan mound complex reached a climax in Subunit IB, which contains a thick floatstone to rudstone interval with highly diverse bryozoan growth forms.
