Article Reference The first record of Early Devonian ammonoids from Belgium and their stratigraphic significance
The first ammonoids from the Lower Emsian (Devonian) of Belgium are described. They belong to the Anetoceratinae, which show the most plesiomorphic characters of all ammonoids. This is the second report of Early Emsian ammonoids within the Rhenish facies of the Rhenish Slate Mountains (Belgium, Germany), in this case from the Belgian part of the Eifel (Burg Reuland). It highlights the possible importance of ammonoids for the correlation of the Emsian in its traditional German sense and the Emsian in the global sense as delimited by the GSSPs. Newly collected, age-significant brachiopods of the genera Arduspirifer and Euryspirifer and other previously reported fossils indicate a middle or late Early Emsian (Singhofen or Vallendar) age (in German sense) for this locality. We extend the range of Ivoites schindewolfi outside of the Hunsrück Basin and further corroborate an age younger than Ulmen for parts of the Hunsrück Slate.

Article Reference Ammonites from the Dababiya Quarry Corehole: Taxonomic notes and age assessment
We describe a small collection of ammonites from the Dababiya Quarry corehole. It is almost entirely composed of heteromorph ammonites, in particular of scaphitids and baculitids. The presence of Indoscaphites pavana (Forbes 1848),which is for the first time reported from Egypt, points to a late to possibly latest Maastrichtian age for the interval DBD 80.36–DBD 99.11 of the Dababiya Quarry core. This is corroborated by preliminary data on planktonic foraminifera.

Article Reference Early Eocene frogs from Vastan Lignite Mine, Gujarat, India
The Ypresian Cambay Shale Formation of Vastan Lignite Mine in Gujarat, western India, has yielded a rich vertebrate fauna, including the earliest modern mammals of the Indian subcontinent. Here we describe its assemblage of four frogs,including two new genera and species, based on numerous, diverse and well−preserved ilia and vertebrae. An abundant frog, Eobarbourula delfinoi gen. and sp. nov., with a particular vertebral articulation similar to a zygosphene−zygantrum complex, represents the oldest record of the Bombinatoridae and might have been capable of displaying the Unken reflex. The large non−fossorial pelobatid Eopelobates, known from complete skeletons from the Eocene and Oligocene of Europe, is also identified at Vastan based on a single nearly complete ilium. An abundant “ranid” and a possible rhacophorid Indorana prasadi gen. and sp. nov. represent the earliest records of both families. The Vastan pelobatids and ranids confirm an early worldwide distribution of these families, and the bombinatorids and rhacophorids show possible origins of those clades on the Indian subcontinent.

Article Reference A bioarchaeological investigation of three late Chalcolithic pits at Ovçular Tepesi (Nakhchivan, Azerbaijan)
Socio-economic organisation, subsistence strategies and environmental exploitation still remain largely open questions for the Late Chalcolithic period (ca. 4500–3500 BC) in southern Caucasus even though they are of prime importance for understanding the development of post-Neolithic societies in these semi-arid and mountainous areas. Interdisciplinary bioarchaeological research can, however, provide valuable new insights into these issues. In the Late Chalcolithic occupation layers at Ovçular Tepesi (Nakhchivan Autonomous Republic, Azerbaijan), the fills of pits, composed mainly of domestic refuse, proved to contain the richest and most diverse assemblages of biological remains at the site. These remains, retrieved by the use of flotation and sieving techniques, therefore constitute ideal assemblages for understanding subsistence strategies and the exploitation of natural resources. It is shown here that the agricultural economy at Late Chalcolithic Ovçular Tepesi was based mainly on the cultivation of cereals and pulses and the herding of sheep and goat. The river and its surroundings provided wood fuel and fish. The results of the bioarchaeological study further suggest that the Late Chalcolithic village was occupied permanently as shown by the development of commensal populations of small mammals.

Article Reference Evidence of sun-dried fish at Mleiha (S.-E. Arabia) in antiquity
A concentration of fish remains found in a single room of a fortified building at Mleiha (United Arab Emirates) is presented here. Part of it was probably the filling of a bag or an organic container that fell from a bench onto the floor of the room. The various species recovered from these contexts, dating to the second to mid-third centuries AD, are briefly described. Particular attention is paid to the skeletal elements by which the fish are represented and to the corresponding lengths of the animals, as these allow the proposition that the fish had been dried on the seashore before being carried to the site inland. The data from building H will be compared to those from previously studied contexts at Mleiha (Gautier & Van Neer 1999; Mashkour & Van Neer 1999). In addition the ichthyofauna from ed-Dur (Van Neer & Gautier 1993), a coastal site that is partially contemporaneous with the contexts from building H, will be considered.

Article Reference In search of the Latest Danian Event in a paleobathymetric transect off Kasserine Island, north-central Tunisia.
Danian (lower Paleocene) sequences in north-central Tunisia are dominantly composed of marls and shales but a conspicuous, indurated glauconite-bearing marker bed is associated with the P3a–P3b transition. This glauconite bed is considered to correlate with the Latest Danian Event (LDE) described from the Nile Basin in Egypt, with the ‘top Chron C27n event’ (Atlantic and Pacific Oceans) and with the ‘CIE-DS1’ (Zumaia, Spain). The LDE is thought to reflect a short period of global warming, similar to the Paleocene Eocene Thermal Maximum, but of lesser magnitude. The presence of a glauconitic bed at the P3a/P3b transition in Tunisia suggests that the sequence is condensed, which is confirmed by planktic foraminifer and nannofossil biostratigraphy, and by the absence of the typical LDE beds found in most Egyptian sections. Benthic foraminiferal assemblages were quantitatively analyzed in three sections in north-central Tunisia (Sidi Nasseur, Garn Halfaya, Elles) in order to characterize the paleoenvironmental evolution during the late Danian and compare this with sections in Egypt. The benthic foraminiferal assemblages indicate that the Tunisian sections were located along a depth- and a paleoenvironmental gradient on the shelf north of Kasserine Island. The reconstructed depth range is comparable with sections in Egypt, and encompasses middle neritic (Sidi Nasseur section) to shallow upper bathyal depths (Elles section,with up to 16% Gavelinella beccariiformis below the P3a/P3b). Like in Egypt, assemblage shifts across the P3a/P3b subzonal transition indicate shallowing and a transition to amore eutrophic paleoenvironment, characterized by relatively high abundances of buliminids and Stainforthia sp. The δ13C and δ18O records generated on well-preserved specimens of the ostracode species Bairdia failed to demonstrate the presence of the carbon isotope excursion (CIE) associated with the LDE at the base of Subzone P3b. A condensed section or a hiatus associated with the glauconite bed would explain why the CIE is not recorded in the Tunisian sections.

Article Reference Eocene initiation of Nile drainage due to East African uplift.
The Late Eocene and Early Oligocene sedimentary succession in the Fayum, Egypt records the progressive development of northerly flowing Nile-type African drainage. New biostratigraphic dating of these units allows the calibration of the paleomagnetic record, the combination of dating methods enabling a detailed chronology of events to be studied. Between about 38 and 35 Ma there was a dramatic change in sedimentary regime and vast quantities of clasticmaterial were transported into the area, smothering the underlying carbonate platform and initiating a stepwise progradation of clastic units. The sudden change in sediment availability coincideswith the beginning of uplift and volcanic activity in the Turkana region of East Africa, cutting off preexisting easterly drainage from the middle of the continent. The Fayum succession therefore records the initiation of northerly drainage of central and eastern Africa, and the origins of themodern Nile watershed. The development of the current route of the Nile, with the incision of the current Nile Valley, was slightly later and related tomid Oligocene uplift of the Red Sea margins and Messinian base level fall.
