First records of conodonts from the late Triassic of Britain
£1.00
Conodont elements have been recovered for the first time from British Triassic deposits. Most specimens are from the Langport Member (Penarth Group, late Triassic) at Normanton Hills, Nottinghamshire, but elements also occur in the same member at Lavernock Point, South Glamorgan, and in the succeeding Pre-planorbis Beds at Barnstone and Blue Hill, Nottinghamshire. Specimens from the Pre-planorbis Beds may be the youngest conodont elements known from north-west Europe. The occurrence of Misikella posthernsteini (Kozur and Mock) in the Pre-planorbis Beds at Barnstone allows correlation with part of the upper Rhabdoceras suessi and Choristoceras marshi zones of the late Triassic of southern Europe, and with beds of Rhaetian age in Japan and Papua New Guinea. Other elements have little stratigraphic value, and may represent the apparatuses of one or two species only.
