Abstract

New Miocene and Quaternary foraminiferid faunas have been recovered from previously unrecorded localities onshore near Penguin and
Strahan, and at nine offshore localities off northwestern, northeastern and southeastern Tasmania. Most Miocene benthic forms found in
these samples are well known from other Tasmanian Tertiary sections but a few previously unreported taxa are recorded in Tasmania for
the first time. Two samples from off northeastern Tasmania are Miocene. The sample from southeastern Tasmania is Early Miocene with
Quaternary overlying it. Pebbles from Ocean Beach, north of Strahan, contain earliest Middle Miocene faunas. Other samples from off
northeastern and northwestern Tasmania contain Quaternary faunas which probably reflect both periods of lower sea level and cool water
and also periods of higher sea level and warmer water.
These samples extend the range of Miocene calcareous sediments much farther south on both west and east coasts of Tasmania. They
also reinforce the pattern of Tasmanian Neogene sedimentation cycles (earliest Early Miocene, latest Early-earliest Middle Miocene, midLate
Pliocene) identified previously.
