Late Paleocene foraminiferal faunas with Chapmanina and Reticulophragmium from offshore southeastern Australia: a Tethyan influence
Samples from off southern New South Wales in approximately 1750 m water depth have yielded late Paleocene faunas of benthic and planktonic foraminifera and other invertebrates. Two faunal associations with a strong Tethyan influence, dominated respectively by Chapmanina conjuncta sp. nov. and Reticu...
