Acodus sp.

Fig. 8M–Q View Fig

Material. 16 specimens ( S elements ) from the Tabita Formation at Mount Arrowsmith; two from unnamed dolomitic limestone unit at Koonenberry Gap .

Remarks. Multicostate coniform elements referred to herein as Acodus sp. are symmetrical or nearly so. At least two types can be distinguished: a quadricostate element ( Fig. 8Q View Fig ) with an anterior costa, posterior costa, and one median costa on each lateral side; and a septicostae element ( Fig. 8M–P View Fig ) with rounded anterior face, a costa along the posterior margin, and three costa on each lateral side. An additional pentacostate element was also recovered. It has a broad anterior face, two costae on each side and a posterior costa along the posterior margin, and cusp star-shaped in cross section. These specimens show some resemblance to the S elements of Acodus comptus (Branson & Mehl) , but with less strongly developed costae in comparison to that species. They might represent a separate species, but the material available now precludes a complete description.
