The present work is focused on the hipparionine remains from the late Miocene to early Pliocene deposits of the Haritalyangar areas, Himachal Pardesh, India. These remains are taxonomically ranked to five genera (Plesiohipparion, Proboscidipparion, Cormohipparion, Sivalhippus, and Eurygnathohippus) and seven species. The described taxa are predominantly known from China, Africa and the Indian subcontinent. Among these, Proboscidipparion is reported for the first time from the Siwaliks; the material assigned to Plesiohipparion sp. is a potential candidate for a new species. Hipparionines from this area have long been poorly known and are helpful to understand the palaeontological context of the Indian Siwalik mammalian fauna. The hipparionines suggest a wide variety of environmental conditions ranging from grasslands to forests.

The Pliensbachian succession of the Central Unit of the South Riffian Ridges domain consists of four formations. The second one, the Jebela Formation, is rich in brachiopods especially at Jbel Dhar N'Sour Anticline. Twenty-three species belonging to three orders (Spiriferida, Rhynchonellida and Terebratulida), and eight genera have been identified in addition of seven species of bivalves. Most of the studied brachiopod taxa are described and illustrated for the first time from the Pliensbachian succession of the South Riffian Ridges domain and Morocco in general. Several of these taxa have wide geographic distributions in the Peritethyan basins of the northern and the southern margins of the western Tethys and the Subboreal Domain of NW Europe.

In the present paper, we describe and figure some rare lower Aptian (Lower Cretaceous) helical ammonoids from the Deshayesites deshayesi Zone of the Argiles à Plicatules Formation (Paris Basin, NE France). Those are the only helical ammonoids known in this zone so far. They were only occasionally evoked in literature and this is probably on the basis of the specimens here described that, according to us, the genus Toxoceratoides (Helicancylidae) was wrongly regarded as possessing an early helical spiral part. We demonstrate here that these specimens are not belonging to Toxoceratoides nor Helicancylidae: they are interpreted as ‘abnormally’ helical representatives of the genus Ancyloceras (Ancyloceratidae) or a new taxon of Ancyloceratidae.

An old find of a graptolite from the Eifelian Jemelle Formation, combined with the recent discovery of an exceptionally well-preserved specimen from the Upper Frasnian (Matagne Formation), allow documentation of the geologically oldest and youngest dendroid fossils from the Devonian of Belgium. Both are ascribed to the long-ranging genus Callograptus (Acanthograptidae). These records enlarge the sparse knowledge of graptolite diversity and occurrences along the southern margin of Laurussia during the mid-Paleozoic. In Belgium, Devonian dendroids are exclusively known from the Dinant Synclinorium. The Devonian dendroid faunas previously reported from the Eifelian, Givetian and Frasnian of the Ardenne–Rhenish massifs (Belgium and Germany) are of low diversity (one to five species per locality). The specimens, generally inedaquatelly preserved, were ascribed to the genera Callograptus, Dictyonema, Palaeodictyota?, and Ruedemannograptus? In these massifs, Carboniferous dendroids are only known from the Viséan (Moliniacian) Denée Konservat-Lagerstätte. Other but undocumented reports of dendroids (and rhabdopleurids) are from the historical type area of the Tournaisian Stage (Tournai area, Brabant Parautochthon). Rhabdopleuridae from the Viséan–Serpukhovian of the Campine Basin (Turnhout borehole) remain incompletely known in the absence of the previously described material.

Miocene scleractinian corals were documented for the first time in the Fırat Formation of Sarıca village, Eğil district of Diyarbakır, SE Turkey. The fauna consists of four hermatypic species belonging to three families: Diploastrea taurinensis (d’Achiardi, 1868), Tarbellastraea reussiana (Milne-Edwards and Haime, 1850), Echinopora gemmacea (Lamarck, 1816) and Montastraea pelouaensis (Chevalier, 1954). The morphospecies described here are typical of the early Miocene (Aquitanian-Burdigalian) and show that the Fırat Formation coral community was composed of shallow and subtropical reefs of Mediterranean Tethys palaeobiogeographical affinity. The examined species are reef components found in tropical and subtropical oceans, as are the majority of zooxanthellae. The species were upper photic zone related, had massive colonial growth morphology, and lived in a shallow tropical-subtropical marine palaeoenvironment at a depth of up to 50 m. They grew on hard ground, clean water, and normal salinity and required a minimum seawater temperature of 18 ̊C; however, they were most abundant at water temperatures ranging from 22 to 26 ̊C in high-moderate water energy. Consequently, this fossil assemblage will not only improve our knowledge of scleractinian coral diversity and morphological variation in SE Turkey but will also provide an important background for future studies of coral taxonomy, diversity and biogeography of the region.

The diversity of praeaulacid wasps in Kachin amber is relatively poorly documented. Here, a new genus and species of praeaulacid wasp are described and illustrated from the mid-Cretaceous Kachin amber as Archeogastrinus kachinensis gen. et sp. nov., and placed in the subfamily Praeaulacinae. This new genus is distinguishable from the other Praeaulacidae because of its particular tibial spurs formula 1-2-2; its forewings with a long and thin pterostigma, a 1-M longer than 1-Rs, a 1-Rs longer than its distance to pterostigma, a crossvein 2r-rs aligned (or nearly) with 2rs-m and originating near the middle of pterostigma, a 2rs-m present, a cell 3rm long, a 1cu-a postfurcal to 1-M, a vein 2-M distinct; its hind wings cu-a reaching Cu distad M + Cu fork; and its metasoma with a first segment petiole-like (i.e., long and thin) and ventrally inflated in its distal half. The position of the genus Mesevania is briefly discussed, as well as the validity of the genus Paleosyncrasis, both described from the mid-Cretaceous Kachin amber.
克钦琥珀中前叶胡蜂的多样性文献记载较少。本文描述了中白垩世克钦琥珀中一个新属和新种,称为Archeogastrinus kachinensis gen. et sp. nov.,并将其归入预胡蜂亚科。这个新属由于其特殊的胫刺公式1-2-2而与其他前肢酸科区分开来;其前翅具一细长的翼柱头,长1 ~ 1米,长1 ~ 2米,距翼柱头1 ~ 2米,与翼柱头近正中平行(或近)的横脉2 ~ 2米,有1 ~ 2米长,室长3米,后径1 ~ 1米,脉2 ~ 2米明显;其后翅Cu -a伸至Cu - distad M + Cu叉;其下半部的瘤具有第一节叶柄状(即长而薄),腹侧膨大。本文简要讨论了Mesevania属的位置,以及古syncrasis属的有效性,这两个属都是在中白垩世克钦琥珀中描述的。

This study deals with the Middle Eocene ostracods from southeast Fayoum area, Egypt. To carry out this investigation, three outcrops are examined, Gebel Elwe El Breig, Gebel Sath El Hadid and Gebel Munqar El-Shinnara. This study is based on the Midawara Formation that consists mainly of fossiliferous limestone, marly limestone and clay. The studied ostracod assemblage includes thirty-one species and subspecies, belonging to twenty-three genera and seventeen families. The ostracod group belonging to Cytheroidea Baird, 1850 represents the most abundant group that reaches 81.99% in Munqar El-Shinnara section, 81.88% in Sath El Hadid section, and 61.12% in Elwe El Breig section. The structure of the investigated assemblages (abundance of ostracods, number of taxa, Fisher's alpha, Shannon index, and equitability) indicates deposition in an environment belonging to the neritic zone. Moreover, this study tries to use the multivariate analyses to distinguish the paleobiogeographic provinces in Tethyan region during the Middle Eocene. These analyses are applied on a matrix consists of some nominated Middle Eocene species from 13 countries. The results point to two distinctive provinces, Southern Tethys Province (Algeria, Tunisia, Libya, Egypt and Jordan) and the Northern Tethys Province (England, Germany, Spain, France, Belgium, Ukraine, Hungary and Turkey). The reasonable similarities between these provinces may reflect a possible connection between both sides of the Tethys during the Middle Eocene age.
本文研究了埃及法尤姆东南部地区中始新世介形类。为了进行这项调查,考察了三个露头:Gebel Elwe El Breig、Gebel Sath El Hadid和Gebel Munqar El- shinnara。本研究以Midawara组为研究对象,该组主要由化石灰岩、泥灰岩和粘土组成。所研究的介形类包括17科23属31种和亚种。属Cytheroidea Baird, 1850的介形虫群数量最多,Munqar El- shinnara剖面为81.99%,Sath El Hadid剖面为81.88%,Elwe El Breig剖面为61.12%。所调查组合的结构(介形虫丰度、分类群数量、Fisher’s alpha、Shannon指数和公平性)表明沉积环境属于浅海带。此外,本研究尝试运用多元分析方法来区分特提斯地区中始新世的古生物地理省。这些分析应用于一个由来自13个国家的一些指定的中始新世物种组成的矩阵。结果指向两个不同的省份,南特提斯省(阿尔及利亚、突尼斯、利比亚、埃及和约旦)和北特提斯省(英国、德国、西班牙、法国、比利时、乌克兰、匈牙利和土耳其)。这些省份之间合理的相似性可能反映了始新世中期特提斯河两岸之间可能存在的联系。

A coracoid of an enantiornithine bird from Upper Cretaceous (probably late Campanian) fluvial sediments at Castigno (Villespassans, Hérault, southern France) is described. It differs from all hitherto reported enantiornithine coracoids and is referred a new genus and species, Castignovolucris sebei. This bone is large and robust, indicating a bird that was among the largest known enantiornithines, possibly the size of a Canada Goose (Branta canadensis). The new taxon is an addition to the short list of Late Cretaceous birds from France and confirms that enantiornithines were an important component of European avifaunas until late in the Cretaceous.

Messinian sedimentation in Tunisia is characterized by the absence of large carbonate platforms known in many Mediterranean marginal basins. As a result, correlations are not easy to establish in order to integrate it into a general pattern of development at the regional level. However, the discovery of microbial constructions of metric scale makes it possible to precise uncertain points. Thus in the sector of Cap Bon in the northeast of Tunisia, stromatolitic constructions can form, over distances of several hundred meters, domes containing columnar structures at different scales as well as carbonate beds showing sedimentary ripples also of microbialite nature. The highlighting of an assemblage of microbialites, associated with oolitic deposits, allows linking these formations to the Terminal Carbonate Complex which finds its place at a part of the so-called Messinian Salinity Crisis.
