Mr. Donald H. Richter c/o Alaska Mineral Resources Branch U.S. Geological Survey 345 Middlefield Road Menlo Park, California Dear Mr. Richter: Your identification of Daonella in your 1971 collections from the Nabesna quad is correct. Both 71-ARh-131 and 71-PCL-305 contain D. degeeri Bohm. This is a better name for the “mid” Ladinian (upper Middle Triassic) species that occurs just beneath the Nikolai Greenstone in the McCarthy C-4 quad. And was referred to D. cf. subquadrata on the GQ Map by Mackeveet (1970). In collection 71-ARh-151, D. frami Kittl is represented in addition to D. degeeri; the age interpretation is, of course, the same. Representative specimens from these collections have been added to the reference collections of the P&S Branch in Menlo Park, and the remaining scraps of matrix have been returned to the Alaskan Branch. |
