Your suite of 11 small collections from Charley River and Eagle quadrangles are unfortunately lacking in any well-preserved fossils that might be of use in critical dating of your sections. The collections and contents are as follow: |

| Comment: | This is the most interesting collection of the lot, but is still of no help in your stratigraphic problems. It contains one branching fern(?) rachis, several large, leafless axes with bulbous bases (these are probably the basal parts of fern rachises), and one fragmentary fern frond with a few pinnules attached. The pinnules are only vaguely visible, but they seem to show a Rhacopteris type of outline and venation. This is suggestive of Mississippian age, but since a positive identification cannot be made, the possibility cannot be discounted that the foliage is of the Early Pennsylvanian Aneimites type. The lithology of this sample is promising of excellent preservation, and if a better sample from this locality were available, I am confident that we could come up with a dependable age determination. If you are in the area again, I would like to urge that a larger collection be made and transmitted here for study. |
