The fossil collections described in letters dated July 6 and 19, 1971 are probably in part of Triassic age as indicated by the presence of monotid pelecypods at locality 71ADt283. The Pliensbachian is represented definitely by Amaltheus at locality 71ADt300C. The late Bathonian, as defined by John Callomon, is represented by Arcticoceras at locality 71ADt330D (or 300D). The Cadoceras from that locality has a black instead of a reddish-brown matrix and appears to have been rounded by rolling. It reminds me of Cadoceras comma Imlay from southern Alaska. It probably comes from higher beds than Arcticoceras, judging by the ranges of those genera in northern Canada and east Greenland. The late Jurassic (middle Kimmeridgian to early Tithonian) is represented by Buchia rugosa (Fischer) at locality 71ADt322. The Buchias from localities 71ADt325 and 325A are probably not specifically determinable but will be sent to Dave Jones. The monotid from locality 71ADt283, will be sent to Norm Silberling. Please check Mes. Loc. 30075 in order to determine proper field number. Also, check all stratigraphic and geographic descriptions and revise as needed. I would like to have your opinion considering the relative stratigraphic positions of Arctocephalites and Reineckeia in the sequence near the Canning River as measured by the BP geologists. Is the position of Arctocephalites above Reineckeia normal or is it due to faulting or folding? |
