Sponge Hindia sphaeroidalis

This porifera or sponge is probably a Devonian period Hindia sphaeroidalis that was embedded in a chert nodule. The odd thing is most references to this sponge are Ordovician but I guess it survived into the Devonian. This sponge was found in the Louisville, Kentucky and must be from the Jeffersonville Limestone.
