Middle Miocene Kangaroos (Macropodoidea: Marsupialia) from three localities in Northern Australia, with a description of two new subfamilies

The middle Miocene macropodoids of the Riversleigh, Bullock Creek, and Kangaroo Well local faunas are the oldest recorded assemblages of kangaroos. Five new species are described here. One, Bulungamaya delicata n. gen. and sp., is placed with Wabularoo naughtoni Archer, 1979 in the new potoroid subfamily Bulungamayinae. Gumardee pascua Ii n. gen. and sp. is placed within the Potoroinae. Balbaroo camfieldensis n. gen. and sp. and Balbaroo gregoriensis n. sp. are placed in a new macropodid subfamily, the Balbarinae. Galanarla tessel/ala n. gen. and sp. is placed in the Macropodidae , but cannot as yet be assigned to a particular subfamily. All the new species are from the Riversleigh local fauna, except B. camfieldensis from the Bullock Creek local fauna. The previously known Kangaroo Well macropodid appears to be referable to the genus Balbaroo. The Bulungamayinae is represented by forms which, although related to potoroines, have bulbous premolars and lophodont molars. The Balbarinae includes generally plesiomorphic forms that may have been ancestral to other macropodids. None of the macropodoid genera described here are known from more recent deposits. This suggests that a radical transition in the dominant kinds of macropodoids took place between middle and late Miocene times.

MH370 Search Phase 1 Raw and Processed datasets

On behalf of Australia, and in support of the Malaysian accident investigation, the Australian Transport Safety Bureau (ATSB) was leading search operations for missing Malaysian airlines flight MH370 in the Southern Indian Ocean. 
Geoscience Australia provided advice, expertise and support to the ATSB to facilitate bathymetric surveys, which were undertaken to provide a detailed map of the sea floor topography to aid navigation during the underwater search. Prior to the bathymetric survey, very little was known about the sea floor in the MH370 search area, as few marine surveys have taken place in the area. Existing maps of the sea floor were coarse, having been derived from satellites and only providing a general indication of water depth. Before the underwater search for MH370 could begin, it was necessary to accurately map the sea floor to ensure that the search is undertaken safely and effectively. Bathymetry survey vessels spent months at sea, scanning the sea floor with multibeam sonar to gather detailed, high-resolution data.
This collation of datasets contains the raw and processed data acquired during Phase 1 of  the search for MH370. Bathymetric data was acquired by multibeam sonar mounted on the hull of multiple vessels (GA survey reference: GA-4421, GA-4422 &amp; GA-4430). Bathymetric surveys were conducted from June 2014 to February 2017, collecting over 710,000 square kilometres of data in the search area and along transit lines (to and from the search area).The raw and processed datasets were acquired from Fugro Equator, Zhu Kehzen, Fugro Supporter between June 2014 and February 2017.

Birrindudu - Frederick, NT, 1997 (P1001), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This Birrindudu - Frederick, NT, 1997 (P1001), radiometric line data, AWAGS levelled were acquired in 1997 by the NT Government, and consisted of 81828 line-kilometres of data at a line spacing between 200m and 400m, and 60m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Calcareous microplankton biostratigraphy of the Eocene Browns Creek Clay in the Aire District, Otway Basin of southeastern Australia: an update

In updating the calcareous microplankton stratigraphic record of the lower part of the Browns Creek Clay (the Turritella clays and Notostrea greensand), Otway Basin of southeastern Australia, unexpected problems with significant consequences were encountered.  Assemblages from the base of the formation include two key species, the nannofossil lsthmolithus recurvus (hitherto unknown from this level) and the foraminiferid Acarinina collactea (unknown from this formation until fairly recently)- in association with Neococcolithes dubius, Chiasmolithus oamaruensis, Cyclicargolithus recticulatus, Discoaster saipanensis, Globigerinatheka index, Tenuitella aculeala, T gemma and T insolita. The stratigraphic range of I. recurvus is disjunct (in this respect, I. recurvus resembles the two Eocene foraminiferids T aculeata and G. index in southern Australia): in its lower range I. recurvus is rare, but it is common in its upper range-with a substantial gap in between, within which N. dubius disappears. Elsewhere, including other southern high-latitude sections, A. collactea is known to disappear well below the first appearance datum (FAD) of I. recurvus, and the split stratigraphic range of I. recurvus has not been explicitly reported. Reworking could be the cause of the overlap in the stratigraphic ranges of I. recurvus and A. eollactea at Browns Creek, although a seemingly wide geographic distribution of the association of these two species and N. dubius in southern Australia has been indicated herein. Evidence (including the presence of rare T gemma) has been discussed , favouring I. recurvus (in preference to A. collactea) as a prime evidence for dating the base of the Browns Creek Clay. This base has been correlated with the sequence boundary between the third order cycles 4.1 and 4.2, and dated late Eocene, at about 36.2 Ma. Cyclicargolithus reticulatus disappears near the Turritella clays/Notostrea greensand boundary - within the foraminiferid Hantkenina alabamensis primitiva interval, which has long been accepted as isochronous across southern Australia.  The event of disappearance of C. reticulatus is thought to be at 34.9 Ma, in agreement with a previously given K-Ar age limits for the Hantkenina interval. The combined evidence of I. recurvus and C. reticulatus assigns the lower part of the Browns Creek Clay a late Eocene age, equivalent to low either Zone NP19/20 or Subzone CP15b. A correlation with the foraminiferal zonal interval high P15 to within P16 of the tropics is possible.
