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.

Eleven ammonite species from five localities in the Ieru Formation, western Papua New Guinea, are described. Four are identified with the well known and widely distributed Cenomanian species of the Acanthoceratidae, Calycoceras (Newboldiceras) newboldi (Kossmat), C. (N.) cf orientale Matsumoto and others, C. (N.) annulatum Collignon and Acanthoceras rhotomagense (Brongniart). Other Cenomanian taxa are three indeterminable acanthoceratid species, C. (Calycoceras) sp. nov .(?), Calycoceras subgenus et sp. indet., and Acanthoceras sp. indet., as well as Pachydesmoceras sp. nov. and Chimbuites aff. mirindowensis Wright. The Turonian species Romaniceras deverioides (de Grossouvre) was found with Placenticeras aff. tamulicum (Blanford); several fragments, probably from the Star Mountains, are also referred to P. aff. tamulicum.

Evan Richard Stanley was the first Government Geologist for Papua, from 1911 to 1924. Under difficult conditions, he conducted geological investigations that resulted in more than 50 papers and reports and the first comprehensive accounts (in 1923 and 1924) of the geology and resources of both the New Guinea and Papua territories. He died unexpectedly in 1924.

Samples from the Rudiger Point-Cape Ruge area, New Britain, are not from a conformable late Miocene-earliest Pliocene sequence, as was presumed by previous workers, but rather are of two age groups, one of general middle Miocene age, and a younger group of late Miocene age. A sample of volcanolithic sandstone, NG34B, is of late Pliocene-middle Pleistocene, Zone N.21-Zone N.22, age; this is the youngest marine sediment yet recognised in New Britain. Planktonic Zone N.18 is correlated, at least in part, with a normally magnetised interval.

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.

The Kuta Formation is mainly a limestone deposit which crops out on the flanks of the Kubor Anticline in the Central Highlands of Papua New Guinea. It has been variously regarded as Cainozoic, Permian and Permo-Triassic in age, but is now positively dated as late Norian or Rhaetian (Late Triassic) on the basic of conodonts, molluscs and brachiopods. The Kuta Formation is thus the youngest known Triassic formation in Papua New Guinea. Interpretation of the local stratigraphy is simplified by this dating. It is now apparent that the marine Triassic sedimentation in Papua New Guinea commenced no later than the Anisian (Middle Triassic) and continued, probably uninterrupted, until Rhaetian time. The fossils identified and described include the conodont Misikella posthernsteini Kozur and Mock, 1974, the ammonite Arcestes (Arcestes) cf. sundaicus, Welter, 1914, and some bivalves. The brachiopods Clavigera, Zugmeyerella, Sinucosta, Robinsonella, ?Hagabirhynchia are equally important in dating the assemblage, but will be described in detail separately. All the more closely identified fossils have a Tethyan Provincial aspect except Clavigera which was previously known only from New Zealand and New Caledonia.
