The specimens are so poorly preserved that they cannot be identified. However, there are some Devonian corals with which they can be compared.

Spongophyllum pax Smith, 1945 and S. unperfectum Smith 1945, have closely spaced, nearly flat tabulae, short septa, and a discontinuous, single row of dissepiments. S. pax is closest to the specimens at hand and is supposed to be Middle Devonian.

The Middle Devonian Dendrostella rhenana Frech is similar to the Alaska specimens but has a thicker wall and longer? septa.

The Alaska specimens don't preserve the key characters but I thinkthat they may be Middle Devonian and that they don't argue against a Middle Devonian age if other evidence is favorable.

I have prepared sections of the possible Amphipora. I agree that they cannont be definitely recognized, but feel that they are probable. As you know, I accept Amphipora as indicative of Middle or early Late Devonian age. In summary, this collection contains the following:

Amphipora? sp.

Phaceloid rugose coral, indeterminate

The collection is probably of Middle or early Late Devonian age.

This one paragraph can be used or quoted if your wish--my wanderings on what the coral might be are for internal consumption only and must not be quoted.

The ?Amphipora is poorly preserved and its identity uncertain. Amphipora in my Great Basin experience appears in the late Middle Devonian (lower Devils Gate). However, the Russians have repeatedly identified Amphipora in the Silurian and I have associated in the same piece with Zelophyllum from the north end of Heceta Island, Alaska, where it seems to be at about the same stratigraphic position with Conchidium alaskense.

My first impulse was to call this coral-bearing limestone Silurian and I believe the evidence continues to favor a Silurian age, though the possibility of Amphipora may weaken this determination.
