Abstract

The Climie Formation, which is about 460 metres thick in the type section of the
Dundas Group, contains the youngest known fossils within the Dundas Group. Just south
of the Murchison Highway bridge over the Dundas Rivulet the Climie Formation is overturned,
sheared and contains poorly preserved fossils in two main horizons, which are
well exposed in road cuttings.
The lower fauna occurs about 200 metres below the top of the formation, while the
upper fauna occurs about 145 metres below the top of the formation. The lower fauna
contains the inarticulate brachiopods Angulotreta(?) sp., and Lingulella(?) sp., plus
the trilobites described herein as Olenus sp., Neoagnostus sp., Agnostus sp., and
Ceratopygidae, gen et sp. indet. Five fragmentary trilobite specimens are left in
open nomenclature. The upper fauna contains the inarticulate brachiopods described
herein as Lingulella(?) sp., and Acrotretidae, incertae sedis plus the trilobites
Agnostus sp., Lotagnostus(?) sp., Peltura(?) sp., and an unassigned member of the
Olenidae. It is suggested that the lower fauna is probably of early post-Idamean age,
with the higher fauna being slightly younger. Both faunas are of a cosmopolitan
nature and indicate easy communication with the open ocean at the time of deposition.
