Cornulites on Rafinesquina Brachiopod

Interesting fossils in this picture of a brachiopod shell hosting a number of worm tubes. These fossils are from the Ordovician Period and were found in the Lexington Limestone(?) in Franklin County, Kentucky.

There appear to be 15 worm tubes (Cornulites) on the Rafinesquina brachiopod shell. Apparently the brachiopod was dead when the five attached themselves to the inside of the shell.

Approximately 10 Cornulites attached to the outside of the shell.


View of five worm tubes attached to inside of the shell.
