Bryozoan Fossil Sand

The SFMS has liability insurance has available to member clubs. That makes field trips to quarries possible. This sand was collected on a field trip to a quarry in Tennessee. It is mostly tiny, silicified (replaced by silica) bryozoans. Bryozoans are marine invertebrates that live in colonies similar to coral.
