Article: Planicardinia, a new septate dalmanellid brachiopod from the Lower Devonian of New South Wales
Planicardinia is described as a new genus of septate dalmanellid occurring in deposits of probable early Siegenian age in New South Wales. The new genus, known only by the type species Planicardinia carroli sp. nov., is placed in the Mystrophoridae together with the genera Mystrophora, Kayserella, and Hypsomyonia. It is the earliest known representative of the family and its presence at this horizon indicates that the origins of the group are at least as old as the early lower Devonian.
