[Note by R.B. Blodgett: See transmittal sheet submitted by I.L. Tailleur, dated Oct. 17, 1963, for Shipment A-63-30. He submitted collection made from Russ Campbell's locality (60ACr-105), Tailleur's locality 63ATr334 (USGS loc. 19771-PC), was reported on by Dutro in his E&R report of 5/27/68, who indicated that the exposure was Mississippian in age.]

Collection 60ACr130, composed of several very small horn corals, probably represents the Siksikpuk formation. Both genera identified by Helen Duncan are reported elsewhere from the Siksikpuk and Tachylasma is not known from pre-Permian rocks.

Of the remaining 5 collections, one contains essentially coralline and bryozoan material (60ACr78) like that found low in the Alapah and its equivalents. This would suggest a correlation with the lower part of unit Ml₃.

The other collections contain elements of what appears to be a single fossil assemblage, composed predominantly of brachiopods, with abundant Leiorhynchus. This is a facies fauna that occurs in the "Culm" lithology nearly everywhere it is present. In relation to the measured section, these fossils could represent either the lower part of Ml₃ or Ml₁. It is quite possible that a shaly facies represents the entire Ml₁ - lower Ml₃ interval in other parts of the Lisburne peninsula.

On the other hand, because there are apparently Devonian and Permian rocks in the same general area, structural complications may have made the identification and distinction among shaly units very difficult.

Collection 60ACr105, the stratigraphic position of which was listed as not well established, contains corals of Devonian aspect according to Miss Duncan. The fossils have been given to W.A. Oliver, Jr. for examination.
