Product Description

Rock Type:  Fossiliferous limestone

Location:  Georgian Bay Formation, Manitoulin Island

Description:  The fossil is a Bryozoan.  Several of the fossils were recrystallized to calcite and are subsequently replaced, in part, by fine-grained equigranular dolomite-ankerite solid solution. The fine-grained dolomite that makes up much of the matrix interstitial to the fossil is intercalated with very fine, dark brown clays.
