Like all ...The Upper Pennsylvanian Finis Shale Member of the Graham Formation, Cisco Group (Virgilian Series) can be characterized by its foraminiferal assemblage. Although the chronostratigraphic position of the Finis Shale has been disputed for most of this century, the occurrence of Virgilian age foraminifera supports recent research placing the Finis at the base of the Cisco Group.Fusulinid zonal boundaries that were based on only fusulinid species ranges were found to closely approximate maximum sea level lowstands.

(4.0 centimeters across at its widest) This small piece of fossiliferous limestone is dominated by fusulinids, an extinct group of unicellular, marine benthic organisms (Protista, Granuloreticulosa, Foraminifera, Fusulinina). They had relatively large, elongated, rice-like, microgranular, calcareous skeletons (tests).Fusulinid fossils in the limestone indicate that the rocks formed in the Late Permian or Early Triassic period. Most of the rocks that comprise the San Juan Islands are considered parts of accreted terranes. The rocks and their fossils speak of exotic origins, bits and pieces of the ocean floor and island arcs that came from far away. ...Kireeva, G.D. 1964: On the taxonomie analysis of the wall structure of certain fusulinid genera from the border between the Middle and Late Carboniferous Voprosy Mikropaleontologii 8: 53-56.
