Title: Report on Referred Fossils ,  1968 (12/03)
All of the collections covered by your request of October 10, and thought to contain corals, are included in this report. The collections are grouped as indicated on your page 5, and under the same headings. From my point of view the first three group are logical as the collections in each of these groups seem to be of the same age. --- Some collections in the El Capitan Passage Group are definitely Devonian while others are more likely Silurian. I should emphasize however that all collections in this group may be Devonian.

Referred by: A. Thomas Ovenshine
Age: Silurian (Silurian?)
Comment:These three collections (68AEs117, 68AEs126, 68AEs122) all contain the same species of a small Tryplasma? and are probably the same age. This could be anywhere in the range Middle Silurian to Middle Devonian but the species is more like described Silurian forms so my guess is Silurian.
