Territorial sea boundaries as established under Article 3 (4) and Annex 3 of the Treaty between Australia and the Independent State of Papua New Guinea concerning Sovereignty and Maritime Boundaries in the area between the two Countries, including the area known as Torres Strait, and Related Matters (1978) Diagram AU/PNG-14

This series of maps covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent.

At this scale 1cm on the map represents 1km on the ground. Each map covers a minimum area of 0.5 degrees longitude by 0.5 degrees latitude or about 54 kilometres by 54 kilometres. The contour interval is 20 metres. Many maps are supplemented by hill shading.

Middle and Late Jurassic and some Early Cretaceous Belemnitida collected mostly within the region covered by the Ok Tedi and Mianmin 1:250 000 sheets in the central highlands of Papua New Guinea are identical with those of eastern Indonesia. Conodicoelites kalepuensis confirms that part of the Maril Formation is Bathonian in age. Members of the Belemnopsis moluccana-B. galoi-B. stolleyi lineage which spans the Late Jurassic of Indonesia confirm that the Imburu Mudstone and Upper Maril Formation are Oxfordian- Late Tithonian in age. Hibolithes australis n. sp. spans the Late Tithonian-earliest Berriasian interval; Belemnopsis jonkeri and Hibolithes gamtaensis n. sp. range from Berriasian to Valanginian confirming these ages for the Toro Sandstone, basal Ieru Formation and basal Tubu unit. Hibolithes taylori n. sp. (Aptian- Albian), Parahibolites jeraminensis n. sp. (Albian) and Dimitobelus macgregori (Albian- Cenomanian) are present in the Upper Ieru Formation and Chim Formation. The presence of Hibolithes taylori in outcrops previously mapped as Toro Formation suggests that the Aptian- Albian Omati Unit has been wrongly identified as Toro Formation in some instances.

A new zygomaturine diprotodontid, Hulith erium tomasellii gen. et sp. nov., from 38 000-year-old swamp sediments at Pureni, Southern Highlands Province, Papua New Guinea is the largest mammal yet known from the Quaternary of New Guinea. Possibly the sister taxon to species of Zygomaturus, the new genus is represented by a partial skull and parts of the postcranial skeleton. Estimated to have weighed 75-200 kg, H. tomasettii was probably a browser. Its hindlimb morphology suggests that it had a greater joint mobility than is known in any other diprotodontid, and this in turn hints that it was probably not graviportal.
