Mississippian Period Bryozoan Fossil with Holdfasts

This picture shows what appears to be a Fenestella bryozoan fossil. While a common fossil to find in the Louisville area when looking a Mississippian age rock, finding one with narrow tube like holdfasts is somewhat rare. It was found in the Glen Dean Member of Grayson County, Kentucky, USA. The fossil dates to the Mississippian Period.

Thanks to Kenny for the image.
