A solitary type of coral found commonly in the local limestone/marine layer. I have been told the two examples below are perhaps of two different species.
The first piece is assumed to be Stereostylus.
The second piece that is split down the middle was thought to perhaps be
Lophophyllidium. That would be odd, as it is supposed to occur within the Vanport Limestone.
Stereostylus
