Reworked Silurian and Ordovician conodonts from the Late Devonian Catombal Group, central western New South Wales

Reworked conodonts, extracted from calc-lithic horizons within the Late Devonian Catombal Group, central western New South Wales, are identified as being derived from horizons correlated with the following Silurian zones: Kockelella amsdeni, Pterospathodus amorphognathoides, Distomodus staurognathoides and possibly Distomodus pseudopesavis and Distomodus combinatus. Several Ordovician elements were also recovered but only a broad Middle to Late Ordovician age can be determined. Comparisons of these faunas with those documented from the general region indicate a probable source from limestone sequences to the south, between Orange and Cowra.
