Abstract. The present paper includes detailed descriptions of all fossil fishes known from the Los Rastros Formation (Ladinian; Bermejo Basin, Argentina). Four taxa are identified: Gualolepis carinaesquamosa  n. gen. n. sp., Rastrolepis  n. gen. with two species R . riojaensis n. sp. and R. latipinnata n. sp., and Challaiaelongata n. comb. Gualolepis  n. gen. and Rastrolepis n. gen. are incertae sedis actinopterygians. The opercular bones of Gualolepis resemble those in peipiaosteid acipenseriforms and the fish might be related with the Chondrostei. The most distinctive features of Rastrolepis are the narrow opercular region and the presence of a very large plate-like branchiostegal bone resembling the condition in the Redfieldiiformes. Challaiaelongata, originally described in the Australian genus Myriolepis, is here refered to the genus Challaia, previously known from the nearby Cuyo Basin and representing the first fish taxon common to both continental sequences. Furthermore, Challaia is shown to be a member of the Acrolepidae and represents the youngest record of the family in Gondwana. Alle fossilen Fische, die bisher von der Los Rastros Formation (Ladin; Bermejo-Becken, Argentinien) bekannt sind, werden im Detail beschrieben. Vier Taxa können identifiziert werden: Gualolepis carinaesquamosa  n. gen. n. sp., Rastrolepis  n. gen., mit zwei Arten, R . riojaensis  n. sp. und R . latipinnata  n. sp., und Challaiaelongata comb. nov. Gualolepis  n. gen. und Rastrolepis  n. gen. Actynopterygier unsicherer systematischer Stellung. Die Operkular-Knochen von Gualolepis ähneln jenen der peipiaosteiden Acipenseriformen und das Taxon mag mit den Chondrostei verwandt sein. Die auffälligsten Merkmale von Rastrolepis sind die sehr schmale Operkularregion und das Vorhandensein eines sehr großen, plattigen Branchiostegale, das dem Zustand in Redfieldiiformen ähnelt. Challaiaelongata, ursprünglich zu der australischen Gattung Myriolepis gestellt, wird hier der Gattung Challaia zugeordnet, die bisher nur aus dem nahegelegenen Cuyo-Becken bekannt war und repräsentiert somit das erste Fisch-Taxon, das in beiden Sequenzen vorkommt. Zudem kann gezeigt werden, dass Challaia zu den Acrolepidae gehört und somit den jüngsten Nachweis dieser Gruppe in Gondwana darstellt. doi:10.1002/mmng.200600011

ABSTRACTSpecimens of trematopid amphibians from the Asturian (Upper Carboniferous) of Nýřany, Czech Republic, are redescribed as two taxa, namely Mordex calliprepes Steen and Mattauschia (gen. nov) laticeps Fritsch. Mordex calliprepes is represented by a single post-metamorphic specimen and has the diagnostic trematopid characters of the nasal region. Mattauschia laticeps is represented by one adult partial skull and mandible plus some fragments and two small post-metamorphic specimens including the species name-bearer. It has the trematopid-type modified lacrimal and a large but oval naris and appears to be the most primitive trematopid yet described. The stratigraphically sequential large trematopids Mattauschia, Fedexia, Ecolsonia and Acheloma show progressive acquisition of the derived features that characterise the terminal form Acheloma.Mordex has a combination of primitive and derived characters and its position within the family is less clear. The many ‘branchiosaurs' in the Nýřany assemblage include specimens that could be larvae of both Mordex and Mattauschia but certain attribution is not possible and they are assigned to Olsoniformes incertae sedis. Mordex and Mattauschia appear to be terrestrial exotic elements in the Nýřany tetrapod assemblage, but with possible larvae in the lake assemblage. Representatives of at least four Palaeozoic dissorophoid families were present in late Middle Pennsylvanian/Asturian strata implying diversification of the Dissorophoidea prior to this time.

AbstractThe family Nemasomatidae is redefined to include onty genera with all sterna secondarily free from pleurotergites. Comments are given on the included genera, viz., Antrokoreana, Basoncopus gen. n. (type-species B. filiformis sp. n.) (Kazakhstan), Dasynemasoma, Thalassisobates, Sinostemmiulus, Nemasoma, and Orinisobates. Isobates coiffaiti Demange, 1961 is synonymized with Thalassisobates littoralis (Silvestri, 1903). Orinisobates is revised and shown to include O. soror sp. n. (Kuril Islands), O. microthylax sp. n. (Kamchatka and Siberia), O. gracilis (Verhoeff, 1933) (NW China), O. sibiricus (Gulicka, 1963) (Altai region, Kazakhstan), O. kasakstanus (Lohmander, 1933) (Kazahkstan), O. nigrior (Chamberlin, 1943) (eastern United States), O. utus (Chamberlin, 1912) (northwestern United States), and O. expressus (Chamberlin, 1941) (northwestern United States and adjacent Canada). Mimolene oregona Chambertin, 1941 and M. sectile Loomis & Schmitt, 1971 are synonymized with O. expressus. A possible case of parthenogenesis in O. microthylax is recorded. Evidence is presented for the following sister-group relationships: Antrokoreana + (Basoncopus + (Dasynemasoma + (Thalassisobates + (Sinostemmiulus + (Orinisobates + Nemasoma))))). The position of Basoncopus is uncertain, and O. soror may belong in a separate genus and constitute the sister-group of Orinisohates + Nemasoma. If soror does belong in Orinisobates, it is the sister-group of all its congeners. The American species of Orinisobates are shown probably to constitute a monophyietic group. The family is suggested to have originated in the eastern Palearctic region, Orinisobates having invaded North America via the Bering Bridge. Doubtful species and species erroneously assoiciated with the Nemasomatidae are listed. The genera Okeanobates and Yosidaiulus are excluded from the family and referred to Okeanobatidae stat. n. in superfamily Blaniuloidea. The genera Trichonemasoma, Telsonemasoma, and Chelojulus are also excluded from the Nemasomatidae and relegated to Julida incertae sedis.

Palaeacmaea typica, the type species of the genus, and P. irvingi, the only other Late Cambrian taxon considered congeneric are redescribed herein. Their morphology suggests that they are neither Monoplacophora, where they are currently assigned, nor are they Mollusca. Specimens of P. irvingi demonstrate considerable variation in shape, interpreted as distortion of a flexible integument, of essentially no thickness. A neotype is designated for P. irvingi; it is interpreted as a medusiform fossil, possibly a cnidarian. Only the holotype of P. typica is known, but it shows comparable features. The genus and the family Palaeacmaeide are placed in Phylum Incertae Sedis. Four Ordovician species previously assigned to Palaeacmaea, show none of the characteristics noted, and they are tentatively reassigned to other genera.

Taxonomic Changes

The coreine tribe Leptoscelini is subsumed under the tribe Anisoscelini, which receives the genera Leptoscelis LaPorte, Malvana Stål and Phthia Stål. The genus Amblyomia Stål, lacking numerous characters of the tribe, is placed in incertae sedis. Other genera tentatively placed in the tribe include: Coribergia Casini, Dalmatomammurius Brailovsky, Kalinckascelis Brailovsky, Leptopelios Brailovsky, Leptostellana Brailovsky, Malvanaioides Brailovsky, Onoremia Brailovsky, Plunentis Stål, and Sephinioides Brailovsky. Ugnius Stål and Bellamynocoris Brailovsky are removed from Acanthocephalini to Anisoscelini.

ABSTRACT Fructifications of epiphyllous fungi were encountered during palynological investigation of the Lower Oligocene shallow-marine deposits of the Krabbedalen Formation at the Savoia Halvø, Kap Brewster, central East Greenland. Six fossil taxa from the family Microthyriaceae (Phragmothyrites kangukensis Kalgutkar, Phragmothyrites sp., Plochmopeltinites sp., Trichothyrites cf. ostiolatus (Cookson) Kalgutkar & Jansonius, Trichothyrites sp. 1, and Trichothyrites sp. 2) and one incertae sedis fungal remain are reported. Fungal remains from the Krabbedalen Formation represent the youngest, Oligocene occurrence of the epiphyllous fungi in the Palaeogene of the Arctic. The presence of epiphyllous, microthyriaceous fungi in low quantities and in low taxonomical diversity points to a humid and not necessarily warm climate, which is corroborated by data obtained from the analysis of microscopic plant remains.

AbstractThe fragmentary pterosaur material from the Campanian Grünbach Formation (Gosau Group) of Muthmannsdorf (Austria), previously identified as Ornithocheirus buenzeli Bunzel, 1871, is revised. A lower jaw fragment shows a helical type of articulation, which is known in several families of pterosaurs, and cannot be identified with great accuracy. The proximal part of a humerus shows distinctive features that allow it to be referred to as a member of the family Azhdarchidae, which is widespread in the Late Cretaceous Period of Europe. Ornithocheirus buenzeli is considered a nomen dubium. The pterosaur material from the Grünbach Formation cannot be used as evidence for the presence of ornithocheirids in the Late Cretaceous of Europe.

BackgroundAlthough transient psychotic disorders are currently classified as a category separate from schizophrenia (SZ) and affective disorders, their distinctive features remain uncertain. This study examines the family psychiatric morbidity of the ICD-10 category of ‘acute and transient psychotic disorders’ (ATPDs), pointing out differences from SZ and bipolar disorder (BD).MethodFrom a cohort of 2.5 million persons, we identified all patients enrolled in the Danish Psychiatric Register who were ever admitted with ATPDs (n=2537), SZ (n = 10639) and BD disorder (n=5292) between 1996 and 2008. The relative risk (RR) of ATPDs, SZ and BD associated with psychiatric morbidity in first-degree relatives (FDRs) was calculated as the incidence rate ratio using Poisson regression.ResultsThe RR of ATPDs [1.93, 95% confidence interval (CI) 1.76–2.11] was higher if patients with ATPDs had at least one FDR admitted with any mental disorder than patients without family psychiatric antecedents. An additional risk arose if they had FDRs admitted not only with ATPDs (RR 1.60, 95% CI 1.33–1.92) but also with SZ (RR 2.06, 95% CI 1.70–2.50) and/or BD (RR 1.55, 95% CI 1.23–1.96). Despite some overlap, the risk of SZ (RR 2.80, 95% CI 2.58–3.04) and BD (RR 3.68, 95% CI 3.29–4.12) was markedly higher if patients with SZ and BD had FDRs admitted with the same condition.ConclusionsThese findings suggest that family psychiatric predisposition has a relatively modest impact on ATPDs and argue against a sharp differentiation of ATPDs from SZ and BD.
