The chirostyloid squat lobster Pristinaspina gelasina from the Upper Cretaceous of Alaska is most closely related to members of the genus Kiwa (Kiwaidae) as indicated by the presence of supraocular spines, a medially carinate rostrum and similar carapace groove patterns. Evidence from morphology, stratigraphic position and molecular divergence estimates of extant chirostyloids supports its position in the stem of Kiwaidae. Pristinaspina, however, also differs significantly from kiwaids and is here assigned to a new family, Pristinaspinidae. The chief distinction between the free-living pristinaspinids and vent- or seep-associated kiwaids (and an important synapomorphy of the latter) is the enlargement of the metabranchial regions in kiwaids, which meet in... |

Apart from the common cricetid fauna, the site of Vieux-Collonges contains a number of rare forms: Lartetomys, Melissiodon, Neocometes, and Anomalomys. This scarce material is described and compared with material from other European localities. The stratigraphie position of Vieux-Collonges is discussed briefly. En plus des Cricetodontinae et Cricetinae communs, il existe à Vieux-Collonges plusieures espèces d'autres groupes de Cricetidae, représentées par des matériaux peu nombreux. Il s'agit de Lartetomys mirabilis, Lartetomys zapfei, Melissiodon aff. dominans, Neocometes similis et Anomalomys sp. Cettes formes sont décrites, et leur valeur pour la corrélation de Vieux-Collonges avec d'autres gisements de mammifères miocènes est discutée. |

The hominid bearing strata from the Liang Bua cave on Flores have yielded a large amount of microvertebrate remains. Among these are three mandibles of shrews, the first record of fossil insectivores from the island. The fossils, representing two different species, are not referable to any of the known Recent shrews from Flores, and are probably part of the extinct insular fauna. Since mandibles alone do not offer sufficient characters to allow even a generic classification, they are published in open nomenclature as Crocidura or Suncus sp. A, and sp. B. Από τα στρώματα με Hominidae από το σπήλαιο Liang Bua της νήσου Φλόρες έχει ανασκαφτεί ένας σημαντικός αριθμός ευρημάτων μικροθηλαστικών. Μεταξύ αυτών και τρεις γνάθοι μυογαλής, που αποτελούν τη πρώτη... |

Fossil Hystrix material from a large number of localities is biometrically analysed and compared with the extant species. H. major, H. etrusca, H. makapensis, and H. angressi are shown to be junior synonyms of H. refossa. H. bessarabica and H. trofimovi are shown to be junior synonyms of H. primigenia, and H. schaubi and H. cristata minor of H. vinogradovi. The dental characteristics of H. refossa, H. primigenia and H. vinogradovi are discussed. |

Up to now the genus Holectypus Desor (1842, p. 52) 1847, (cf. Mortensen, 1948, Monogr. IV 1, p. 26) in its restricted sense (with 4 genital pores) has not been recorded from the Senonian. So the two specimens described below as H. boschmai nov. spec. may have been remaniated and finally deposited in the Senonian of South-Limburg. They then may belong to the Jurassic species H. corallinus d'Orbigny, 1850. Though the preservation of two other specimens of Holectypus from the Limburg Senonian does not permit to decide whether a fifth genital pore is present, it is presumed there was. These two specimens are described as H. macrostomus nov. spec. As said, up to now no Senonian Holectypus is known with 4 genital pores. Holectypus boschmai nov. spec. (pl. XIV)... |

The fauna of Muridae (Rodentia) from the Lower Turolian of Crevillente (Alicante, SE Spain) contains species attributed to the genera Huerzelerimys, Parapodemus, and Occitanomys. The material described allows a detailed biostratigraphy of Upper Miocene deposits of SE Spain. En este trabajo se estudian tres generos de Muridae (Huerzelerimys, Parapodemus y Occitanomys) procedentes de varios yacimientos del Mioceno final de Crevillente (Alicante). Las faunas encontradas permiten precisar la bioestratigrafia de los depositos del Turoliense inferior del SE de Espana. |

A sirenian skeleton, the major part of which was excavated from Miocene deposits at Eibergen near Winterswijk, belongs to Metaxytherium. The temporal crests on the parietals are well separated. The foramen magnum is pointed above. The mandible has a downturned symphysial body with four shallow alveoli on each side. The wide mandibular canal opens some distance behind the alveolus of M3. There are alveoli for one premolar (P4) and for three molars (M1-M3). Only M2 dext. is preserved; it has four main cusps and some accessory cusplets. The humerus, the shaft portion of which is missing, has a wide and marked bicipital groove. The vertebrae, with the exception of the atlas, are fragmentary. The spinous processes are solid, the centra porous. The ribs, a few... |

This paper deals with four cricetid genera that were formerly assembled under the genus names Democricetodon and Fahlbuschia. Four new species are described, Fahlbuschia decipiens, Fahlbuschia corcolesi, Renzimys lacombai, and Pseudofahlbuschia jordensi gen. nov., sp. nov. The material studied is placed in its stratigraphic context, and appears to be most valuable for a stratigraphic subdivision of the Aragonian. The evolution and paleoecology are discussed. |

Between c. 23 and 8 Ma, western Amazonia was occupied by the vast Pebas long-lived lake/wetland system. The Pebas system had a variety of influences over the evolution of Miocene and modern Amazonian biota; it formed a barrier for the exchange of terrestrial biota, a pathway for the transition of marine biota into freshwater Amazonian environments, and formed the stage of remarkable radiations of endemic molluscs and ostracods. The lithological variation of the Pebas Formation has furthermore enhanced edaphic heterogeneity in western Amazonia, sustaining present-day high terrestrial diversity in the region. |

The type and only specimen of Fibrocoelia tubantiensis Van Kempen, that was housed in the palaeontological collection of the Geological Institute of the University of Amsterdam, has been reposited in the Netherlands Centre for Biodiversity – Naturalis, Leiden, the Netherlands. Syltrochos pyramidoidalis Von Hacht, placed in an uncertain order and family by Finks & Rigby, is revised on the basis of new material. This has revealed that the skeleton is composed of spheroclones, so that the species has to be assigned to the Astylospongiidae von Zittel. The species name Carpospongia langei Von Hacht is invalid, being a junior synonym of Carpospongia pogrebowi Asatkin. |

In 1876 beschreef Van Beneden (1876: 799) resten van een kleine zeehond uit het Scaldisien van het Bekken van Antwerpen als Phocanella minor. Newton (1891: 19/20) meldde een humerus fragment van deze soort afkomstig uit het Nodule Bed van de Red Crag bij Foxhall, 4 mijl Z.W. van Woodbridge in Suffolk. Een fragment van een femur werd door Van Deinse (1927: 1363) gerapporteerd van de Groeve van Wiegerink ten noorden van Zwolle; dit zou tot nu toe de enige fossiele vondst van Phocanella minor uit ons land zijn. Het zwarte botje waarvan hier nu melding wordt gemaakt ontving ik van Dr. P. H. de Buisonjé en is afkomstig van een schelpenzuiger in de Westerschelde. Het is een groot deel van het heiligbeen (sacrum), en de overeenkomst met het sacrum van Phocanella... |

The late Eocene ‘soft’ sponge fauna of southern Australia is reconstructed based on disassociated spicules and is used to interpret the paleoecology and environmental context of shallow marine communities in this region. The reconstructed sponge association was compared with coeval sponge assemblages from the Oamaru Diatomite, New Zealand, and with the modern ‘soft’ sponge fauna of southern coastal of Australia. Based on the predominance of shallow- and moderately shallow-water species, the late Eocene assemblage is interpreted to have inhabited waters depths of about 100 m. This contrast with the spicule assemblage from New Zealand, which characterized deeper waters based on the presence of numerous strictly deepwater sponge taxa, and the absence of... |

In the St Cassian fauna of Late Triassic (Early Carnian) age gastropods with protoconch coiled in opposite direction to the teleoconch are common and belong to a number of quite different taxa. Twenty nine of these are here described, 11 of them for the first time: Promathilda misurinensis sp. nov., Turrithilda cassiana sp. nov., T. dockeryi sp. nov., Tirolthilda seelandica gen. et sp. nov., T. nuetzeli sp. nov., Tofanella cancellata sp. nov., Cristalloella cassiana gen. et sp. nov., C. sinuata sp. nov., C. delicata sp. nov., Stuorilda cassiana gen. et sp. nov., and S. tichyi sp. nov. All are newly defined and placed in the Mathildoidea. This connects the Triassic species of that superfamily with the modern Heterostropha (= Heterobranchia). In the family... |

Crustaceans remain poorly known from the Miocene of Jamaica. Herein, we report three species from the upper Miocene August Town Formation of Fowl House Spring, parish of St. Thomas, southeast Jamaica; poorly preserved propodi of a mud shrimp, “Callianassa” sp.; the anterior part of the carapace of Mithraculus sp. aff. Mithraculus coryphe (Herbst); and the cirripede Tetraclita sp. cf. T. stalactifera (Lamarck). Mithraculus sp. aff. M. coryphe at Fowl House Spring considerably extends the stratigraphic occurrence of the genus in the Antillean region down into the Miocene. Hitherto, fossil T. stalactifera in the Caribbean was known from the Plio-Pleistocene of Curaçao and the Pleistocene of Venezuela. |
