| The analysis of early Kasimovian (Pennsylvanian) brachiopod assemblages from two fossiliferous localities of the Las Llacerias Formation (Ándara Massif, Picos de Europa, northern Spain) improve our knowledge of this fossil group in the Cantabrian Zone. At the Morra de Lechugales Peak (locality 1), marlstones and bioclastic limestones, accumulated in a low energy, subtidal, aphotic setting, characterize a soft muddy sea-floor affected by periodic intense bottom currents and provide a rich assemblage of brachiopods together with other macrofossils. Brachiopod specimens are characterized by their small size (<10 mm) and belong to 38 different taxa. The fossiliferous dark marly limestones at the Castillo del Grajal (locality 2) record a very shallow water,... |

| In the present paper the latest studies on the distribution and biostratigraphy of planktonic gastropods in the Central Paratethys are summarised. The research was carried out on material from Tertiary deposits of Austria, Hungary and Poland, mainly concentrating on the Badenian (Middle Miocene). In Hungary correlations on palaeomagnetic, nannoplankton and pteropod data were done for several boreholes. |

| A large collection of Neozanthopsis americana (Rathbun, 1928) from the Middle Eocene (Lutetian) Cane River Formation in Louisiana, USA, represents the first opportunity to describe the species in detail. Detailed analysis of associated teleost otoliths and other vertebrate remains documents a palaeoenvironmental setting characterised by a soft-sediment, inner-shelf setting with normal salinity under tropical or subtropical conditions. Anatomical and morphometric analysis of 21 of the better-preserved crabs demonstrates that gender discrimination cannot be made from dorsal carapace characteristics and that the sample represents post-juvenile individuals. Exocuticle and endocuticle are preserved on some specimens and document the presence of erect... |

| New records of heteromorph ammonites from the Silesian Unit of the Outer Western Carpathians (Czech Republic) are represented especially by small pyrite steinkerns with suture lines preserved. A lesser proportion of them belongs to representatives of the subfamily Bochianitidae from the Valanginian. Among the most interesting is Baculina rouyana d’Orbigny. Another group consists primarily of lower Barremian Leptoceratoidinae. In addition to commonly occurring species of Hamulinites and Leptoceratoides, an Eoheteroceras assemblage is often found, represented partially by new elements. Heteromorphs from the Northern Calcareous Alps (Austria) come from marly Hauterivian limestones. Ptychoceras meyrati is present through most of the Hauterivian. Well-dated... |

| The Cerro de los Batallones (Los Batallones Butte) is located in the central-northern area of the Madrid Basin, central Spain. Nine vertebrates localities containing a large variety of mammals of Upper Vallesian Age (Late Miocene) have been found associated with the sediments forming the butte. From bottom to top, these sediments consist of magnesian lutite beds (Unit I), paleosols formed of sepiolite and opal (Unit II), and siliclastic, marlstone and carbonate beds (Unit III). The set of ERT profiles developed in Los Batallones Butte have demonstrate that electrical imaging techniques are an estimable tool for the characterization and prospecting of fossil sites developed in fine-grained siliciclastic sequences. These localities contain an exceptionally... |

| The insectivore assemblages from the Ramblian stratotype near Calamocha (Spain) are described, as well as those from San Roque 4A and 4B, two Ramblian localities near the Aragonian stratotype. Two new species are described, the erinaceid Galerix remmerti, and the shrew Clapasorex alvarezae. Both the percentages and the diversity of insectivores are higher in the Lower Ramblian, suggesting more humid conditions in zone Z than in zone A. This is in contradiction with the palaeoenvironmental reconstructions based on rodents. Se describen las asociaciones de insectívoros del estratotipo del Rambliense cerca de Calamocha (Teruel, España), junto de las de San Roque 4A y 4B, dos yacimientos Ramblienses del área-tipo del Aragoniense.

| Fossil and extant suids from Indonesia, ranging in age from Pliocene? to Recent, are revised. All material is ascribed to the genus Sus, except two species found on Sulawesi (Celebes) which belong to Babyrousa and Celebochoerus, respectively. From the ten Recent species and subspecies recognised, one from the Island of Flores - Sus heureni - is described as new. The Recent species are compared with the fossil ones on the basis of the same morphological characters. As a result uniformity is achieved in the classification of the extant and fossil suids. Based on this classification, the phylogeny, evolution and biostratigraphy of the various Javanese species of the genus Sus are discussed. |

| Two deshayesitid ammonite assemblages are described from the Lower Cretaceous succession of the north coast of Hold with Hope, North-East Greenland, and their biostratigraphical significance is assessed. In the earlier assemblage Prodeshayesites cf. bodei and P. laeviusculus occur. The second assemblage contains Deshayesites boegvadi. The presence of P. cf. bodei suggests that the northwest European bodei Subzone of the fissicostatus Zone is represented in North-East Greenland. The occurrence of D. boegvadi, previously recorded only from Kuhn q, probably indicates the later part of the fissicostatus Zone, or the forbesi or deshayesi zones. Other occurrences of Greenland deshayesitid ammonites are discussed briefly. The new finds from Hold with Hope are... |

| INTRODUCTION The present paper contains notes on some recent cats in the collections of the Rijksmuseum van Natuurlijke Historie, Leiden, as well as descriptions of the fossil Felidae in the "Collectie Dubois", Leiden, which its Director Prof. Dubois entrusted to me. The fossils were collected in Java 1) by Prof. Eug. Dubois during his searches for remains of the precursor of man, and with the intention to gather data about the geological age and ecology of this precursor (cf. Dubois, 1888). The age of the deposits from which the fossil cats were collected, has been much discussed. A review of the literature (up to 1931) on this subject has been given by Van Es (1931), who concludes that the Trinilfauna must be referred to the lower plistocene age, while... |

| Reconstructing the body mass of a fossil animal is an essential step toward understanding its palaeoecological role. Length × width (L×W) of the first lower molar (m1) is frequently used as a proxy for body mass in fossil mammals. However, among rodents, Muroidea have no premolar and an elongated m1, whereas other groups have a premolar and a m1 that is not elongated. This leads to an overestimation of body mass in muroids and/or an underestimation in other rodents. To solve this problem we assembled data of upper and lower tooth row length and body mass in extant rodents, and calculated regression equations for all rodents, rodents with premolars, rodents without premolars and for taxonomic groups at superfamily or family level. Data for complete tooth... |

| The Cenozoic bryozoan fauna of Indonesia has been neglected in the past. In this pioneering study, based on new material collected during the two field seasons of the Throughflow project, we describe a total of 51 bryozoan species, comprising 15 cyclostomes and 36 anascan-grade cheilostomes, ranging in age from Early to Late Miocene (late Burdigalian to Messinian), collected from 17 sections located in the vicinities of Samarinda, Bontang and Sangkulirang in East Kalimantan, Indonesian Borneo. Eleven of these species are new: Microeciella nadiae sp. nov., Pseudidmonea johnsoni sp. nov., Cranosina rubeni sp. nov., Parellisina mirellae sp. nov., Vincularia berningi sp. nov., Vincularia semarai sp. nov., Vincularia tjaki sp. nov., Vincularia manchanui sp.... |

| A summary of the molluscan succession at Holywell Coombe, Folkestone, Kent is given. The replacement of arctic-alpine communities of the Late Glacial by the diverse woodland assemblages of the early and mid Post-Glacial are described. The impact of early man on the faunas since the Neolithic is also assessed. This succession is related to the vegetational history by means of pollen analysis and a detailed chronology is provided by radiocarbon dating. This is the most complete and best dated molluscan succession yet known from Britain. |

| Marls assigned to the Coll de Malla Formation (Lutetian) in the area of Vic (Barcelona) and Sarrià de Ter (Girona) have yielded several specimens of a new brachyuran that can be assigned with confidence to the superfamily Majoidea. General carapace shape, the produced and bilobed front, with two longitudinal rounded ridges, the construction of the orbits, the gently arched posterior margin, as well as the strong conical protuberances in the dorsal regions, favour placement in the family Inachidae. The construction and distribution of the axial and branchial regions confirms assignment to the genus Planobranchia. Distinct features seen in the new material, such as the arched epibranchial ridges bounding the urogastric region, the gently arched posterior... |

| The Berriasian — lower Valanginian genus Leptoceras reappears in the lower Barremian sequences of Rumania, where it is represented by at least two species: L. brunneriforme sp. nov. and L. svinitense sp. nov. This record has led to a revision of the so far accepted taxonomic interpretation of the criomorph Barremian Leptoceratoidinae and of their relationship with the Berriasian-Valanginian Protancyloceratinae. In addition, a new species of the genus Hamulinites (H. nicklesi, from the uppermost Hauterivian) provides evidence that the genus Eoleptoceras Manolov should be considered valid. |
