Simosthenurini sp. indet.

Referred material. NMV P216899, left I1.

Remarks. A single small, slightly worn sthenurine I1 is present in the Nelson Bay assemblage ( figs. 1F–H ). It is narrow and rounded allying it with the Simosthenurini , and is sub-triangular in cross-section as in ‘ Procoptodon ’ gilli and ‘ Simosthenurus ’ browneorum ( Prideaux, 2004), but is much smaller than either (crown length ~ 9.3 mm, occlusal length 3.2 mm, occlusal width 3.5 mm). Because of its small size and triangular cross-section it is unlikely to belong to Si. occidentalis (which is robust and oval), suggesting a second species of simosthenurin is present in the Nelson Bay LF.
