Most of the samples contained Subbotina angiporoides' and 'Guembelitria triseriata which confirm an Early Oligocene age. However at 7 and 8 metres, G. triseriata' was found in the absence of 'S. angiporoides'. While the absence of a species is not sufficient to indicate a different age, the sparsity of foraminifera in the float suggested Late Oligocene. Early Oligocene marine material located nearby at Freds Landing near Tailem Bend and Land lock Point / Magrath Flat have been found to consistently contain prolific planktonic faunas in contrast to Late Oligocene sediments which are generally very poor in planktonic foraminiferal fauna. Neither of these levels can be recorded as belonging to the Ettrick Formation. The exact stratigraphic identity of this sequence is still under review.
