Pentamerid Brachiopods from the Lower Silurian (Wenlock) Canberra Formation, A.C.T., Australia

Desmond L Strusz


Pentamerid brachiopods are rare in the Wenlock-age Canberra Formation, but re-examination of old collections held by Geoscience Australia revealed the presence of four recognisable taxa, described here. The gypiduline Ascanigypa glabra (Mitchell) was originally described from Yass, northwest of Canberra, and has since been recorded from areas farther south; the latter records are revised. The pentamerides are Apopentamerus clarkei Strusz, Kirkidium (Kirkidium) canberrense sp. nov., and Rhipidium (Pararhipidium) oepiki sp. nov.
