The collections were made during studies of the Red Dog massive sulfide deposit in 1998-2004 and in support of regional mapping projects in 1979, 1981, 1983, and 1997-98. The collections--mostly conodonts and some radiolarians--tightly constrain the age of many stratigraphic units of Devonian through Triassic age exposed within the study area, and provide additional data on the depositional environments and thermal history of these rocks. 606 $aConodonts$zAlaska$zDe Long Mountains 606 $aConodonts$zAlaska$zMisheguk Mountain 606 $aConodonts$zAlaska$zNoatak 606 $aRadiolaria, Fossil$zAlaska$zDe Long Mountains 606 $aPaleontological excavations$zAlaska 606 $aGeology, Stratigraphic$yPaleozoic 606 $aGeology, Stratigraphic$yMesozoic 606 $aLithofacies$zAlaska 615 0$aConodonts 615 0$aConodonts 615 0$aConodonts 615 0$aRadiolaria, Fossil 615 0$aPaleontological excavations 615 0$aGeology, Stratigraphic 615 0$aGeology, Stratigraphic 615 0$aLithofacies 700 $aDumoulin$b Julie A$01383035 712 02$aGeological Survey (U.S.) 801 0$bRLA 801 1$bRLA 801 2$bRLA 801 2$bGPO 906 $aBOOK 912 $a9910695917403321 996 $aCondont and radiolarian data from the De Long Mountains quadrangle and adjacent areas, northern Alaska$93510359 997 $aUNINA
