Comment: | Problem: Banjo Point Formation assigned Oligocene or Miocene age by Powers et al. (Bull. 1028P) and Oligocene(?) age by MacNeil (Prof. Paper 553). This is one of several new collecting localities. Hopefully these rocks contain microfossils which will help to determine the age of the Banjo Point Formation with precision. Age: If Foraminifera are in place, probably late Eocene or Oligocene, possibly late Eocene or early Oligocene. Paleobathymetry: Probaly bathyal depths. Remarks: The fauna is characteristic of both shelf and slope faunas with the shelf fauna probably being displaced. |

Comment: | The fragmentary specimens in this collection are too poorly preserved and incomplete to shed any new light on the age of the Banjo Point Formation. The best evidence of age of this formation is furnished by the previous records of Chlamys washburnei (Arnold) (in MacNeil, F. S., USGS Prof. Paper 553, 1967, p. 36-37) which suggest a pre-late Oligocene age. The association of taxa suggests a very shallow water environment but the condition of the fossils could indicate displacement from the original site of deposition. |
