Examination of a single sample from the petroleum well Challis 4 (core 2, 1420.7-1422.16 m) has yielded two conodont elements. One of the elements is identified as Metapolygnathus primitius and the second element, a broken fragment, probably belongs to the same species. This species is found in the M. primitius conodont Zone (Orchard, 1991; Krystyn, 1980) and has been reported in other wells on the North West Shelf (Nicoll & others, ms).
