Discussion:
A nice specimen showing the upper surface of the broad
flat branches
of this type of fenestellid. There are about four rows of zooid chambers
on the tops of the radiating branches of this specimen. There are at least
four places where branches divide to form two branches as it expands
in size. Zooid chambers are usually lacking on the cross bars that join
the branches together.
