        INTRODUCTION. Although not considered as one of the ‘Big five’ mass extinctions (Jablonski, ), the abrupt cooling near the Eocene–Oligocene (E–O) boundary, approx. million years ago (Ma), had great impacts on biodiversity (Katz et al., ; Zhonghui et al., ).During this period, Earth's climate shifted from a relatively ice-free world to one with glacial conditions in Missing: Hantkenina. Oligocene faunas were relatively homogenous between these two regions. During the Eocene radiation occurred in the western Tethys, and abundant and often stratigraphically long-ranging species migrated east and reached Indonesia. This pattern reversed from the Late Eocene onwards, continuing in the Oligocene, and especially the Miocene.

        The book is a comprehensive compilation of all aspects of the geology of Northwest Borneo (Sarawak, Brunei and Sabah) and the contiguous South China and Sulu Seas. The sedimentary formations are described, their palaeontology tabulated and ages discussed. Stratigraphic charts illustrate their relationships across the whole s: 2. We present new paleomagnetic data from Eocene‐Miocene sedimentary rocks in Kutai Basin, Borneo, and compile all available paleomagnetic data from Mesozoic and Cenozoic rocks in Sundaland and Borneo.

Hantkenina in the Eocene of East Borneo. Stanford University, Calif.: Stanford University Press ; London: H. Milford, Oxford University Press, (OCoLC) ABSTRACT: Thefirst record of the genus Hantkenina in the Eocene of Western Australia is discussed.

The species described are Hantkenina (Applinella) cf. dumblei Weinzierl and Applin and Hantkenina (Applinella) cf. longispina Cushman. Associated species offoraminifera indicate a Middle to. Hantkenina  is a distinctive planktonic foraminiferal genus characterized by the presence of tubulospines (robust hollow projections) on each adult chamber, from Middle and Upper Eocene marine sediments worldwide.

Here we illustrate its evolutionary origin using c. specimens from 30 stratigraphic intervals in two sediment cores from Tanzania. This argillaceous sequence is rich in long-ranging planktonic and benthonic foraminifers. Its age is calibrated by the HO of Globorotalia aspensis and the rare occurrence of Hantkenina aragonensis (H.

nuttali) of basal middle Eocene. When the environment is favorable, the ostracod Haplocythere stenzeli also occurs. The Reklaw Formation is Missing: East Borneo.

The continental shelf offshore East Malaysia belongs to an extensive shallow-water area that connects Borneo with the Asian mainland (Fig.

Only the northern part of Borneo is separated from continental Asia by deep water areas of the South China g: Hantkenina. The Eocene-Oligocene boundary is defined at its Global Stratotype Section and Point (GSSP) at Massignano in Italy at a level that corresponds to the extinction of the Hantkeninidae (Premoli Silva and Jenkins, ).Unfortunately, carbonate preservation is poor in the type section, and stable-isotope stratigraphy is unreliable (Bodiselitsch et al., ), so there is uncertainty as to how the Missing: East Borneo.

The Eocene epoch was when the first prehistoric whales left dry land and opted for a life in the sea, a trend that culminated in the middle Eocene Basilosaurus, which attained lengths of up to 60 feet and weighed in the neighborhood of 50 to 75 tons.

Sharks continued to evolve as well, but few fossils are known from this g: Hantkenina. The book is a comprehensive compilation of all aspects of the geology of Northwest Borneo (Sarawak, Brunei and Sabah) and the contiguous South China and Sulu Seas.

The sedimentary formations are described, their palaeontology tabulated and ages discussed. Stratigraphic charts illustrate their relationships across the whole region.

The central part of Borneo is a long arcuate mountain belt that forms the border between Sarawak and Kalimantan and southern Sabah.

It includes a very thick clastic sedimentary succession named the Belaga Formation (Liechti et al., ) in Sarawak (Malaysia) with equivalents in Kalimantan (Pieters et al., ) assigned to the Rajang Group (Hutchison, ) ().Missing: Hantkenina.

East Java is located on the SE margin of the Mesozoic continental core of SE Asia (Sundaland). In this study the region is divided into four east-west trending zones.

The Southern Mountains Zone contains the eruptive products of an Eocene to Miocene volcanic g: Hantkenina. The book is a comprehensive compilation of all aspects of the geology of Northwest Borneo (Sarawak, Brunei and Sabah) and the contiguous South China and Sulu Seas.

The sedimentary formations are described, their palaeontology tabulated and ages discussed. Stratigraphic charts illustrate their relationships across the whole g: Hantkenina. The principal geochemical fingerprint of the Eocene–Oligocene transition (EOT) is an approximately +‰ ‘shift’ towards more positive values of the oxygen isotope ratio of deep-sea.This event was followed by a likely Late Eocene trangression (with Lacazinella in Tiaka wells and at several localities in the Tomori area of East Sulawesi (Handiwiria ) that initiated widespread Late Eocene- Middle Miocene carbonate deposition of the pre.
