Description: South Barrow Test Well 12, lat 71o 14'18"N., long. 156o 20'06" W., Point Barrow area. Barrow (A-4) quadrangle, northern Alaska. Kingak Shale at depth of 2,068 ft. Early Sinemurian. (from Imlay, 1981, p. 24)
    *South Barrow Test Well No. 12 - Microfossil samples from U.S. Navy South Barrow Test Well No. 12 (MF 2759).
Of these 36 samples, 10 contained recognizable foraminifers and the remainder were barren. The foraminifers recovered are rare, mostly poorly preserved, predominantly agglutinated and indicative of a Jurassic age. Samples were represented by well cores taken primarily in sandy facies which no doubt contributed to the poor recovery of microfossils.
