The Tremp basin, North-Spain, is a classical area of paleontological research. From the Upper Cretaceous of this region we know up to now two Sauropods (Hypselosaurus, Titanosaurus) and aniguanodontid Dinosaur (Rhabdodon). Both ischia described in this paper are derived from a Hadrosaur skeleton. This is the first record of the group south of the Pyrenees. It remains uncertain, whether the ischia belong to the only hadrosaurian known from Europe,Orthomerus transsylvanicus, or if they give evidence of an hitherto unknown taxon.  相似文献

Borings from northeastern Germany yielded a gastropod fauna with 31 species from the Upper Toarcian and Lower Aalenian. Eight species have already been described, nine species are new and 14 species are described in open nomenclature. The fauna comes from soft-bottom sediments and is a typical offshore fauna (relatively great distance from the coast, relatively great depth). The fauna has close relationships to faunas of the same age in southern Germany (Franconia).  相似文献

A sauropod tooth, from the Barremian-Aptian ofGalve (Teruel), is described in Spain for the first time. This tooth probably belongs to the sauropod reported by A.F. de Lapparent (1), a Brachiosaurinae different of that reported by J.V. Santafé, M.L. Casanovas & J.L. Sanz (2) and J.L. Sanz, J.V. Santafé & M.L. Casanovas (3) from Morella (Castellón, Spain), Lower Aptian in age. It is probably a lower left piece with a developped worn surface. The subfamily Brachiosaurinae-sensuR. Steel, 1970 (4)-has a certain coherence of tooth morphology in respect of other Camarasauridae-sensuR. Steel, 1970 (4). The piece from Galve belongs to a Brachiosaurinae close to Brachiosaurus, though could differ of this genus in the structure and distribution of enamel ornamentation.  相似文献

A well-preserved macroflora and rich palynological assemblages corresponding to the Camarillas Formation (early-middle Barremian) in the San Cristóbal and Galve Mine sites from the Galve sub-basin in northeastern Spain are presented here. These remains represent the first fossil plant evidence from these deposits. Within plant macroremains, the cheirolepidiacean Pseudofrenelopsis aff. varians (Fontaine) Watson has been found. The palynological assemblage yielded well-preserved spores and pollen grains, mainly dominated by the genus Classopollis. Spores are also abundantly represented by schizaeacean spores (Cicatricosisporites and Plicatella). This spore assemblage supports an early-middle Barremian age for these localities. It is noteworthy that small basal angiosperm pollen grains of the genera Crassipollis and Retimonocolpites, together with other indeterminate grains, have been reported here. This flora constitutes the primary food producer for dinosaur at that time, and thus the information of the flora is important for the understanding of the ecological background for the dinosaur evolution during the Early Cretaceous.  相似文献

A fairly rich ammonite fauna is described for the first time from the Shir-Kuh area. The ammonites represent 18 genera and 31 species. The Desmoceratidae dominate clearly with 62 % beside the Hamitidae with 28%. The remaining fauna shares only 10%. The fauna contains some cosmopolitan elements, but nevertheless is closely related to Europe.  相似文献

Frasnian tentaculites from western part of Central-Afghanistan are described. Six of the 11 studied species are new:Dicricoconus dupliannulatus n. sp.,Dicricoconus ghukensis n. sp.,Dicricoconus gracilis n. sp.,Dicricoconus harundata n. sp.,Volynites kaminjensis n. sp. andAlternatus spatiosus n. sp. The fauna is appearing in two stratigraphic levels. The occurrence ofTentaculites donensis respectively ofDicricoconus tichomirovi, Dicricoconus tragula andUniconus livnensis confirmes the middle-upperfrasnian respectively the upperfrasnian age of both levels. The Devonian basin of Ghuk area was connected with the epicontinental sea of the Russian Plateform throughout the Frasnian and with the Libyan basin at least during upperfrasnian time.  相似文献

A revision of the original material ofStromatomorpha californica var.columnaris Le Maitre 1935 from the Pliensbachian of Morocco and a comparison withStylothalamia dehmi Ott 1967 from the Carnian of Eastern Alps confirm v.Hillebrandts supposition that the two species could be identical. Kurzfassung: Eine Revision des Original-Materials vonStromatomorpha californica var.columnaris le Maitre 1935 aus dem Pliensbachien von Marokko und ein Vergleich mitStylothalamia dehmi Ott 1967 aus dem Kam der Ost-Alpen bestätigen die Vermutung v.Hillebrandts (1971), daß beide Arten ident sind.  相似文献

A rich vertebrate fauna is described from the Middle Muschelkalk (Anis, Triassic) north of Gottingen, West-Germany. Completely preserved juvenile fishes ofEosemionotus vogeli Fritsch 1906 occur besides teeth of selachians, scales and some bones of actinopterygians and actinistians and bones of nothosaurs. Genus and species ofEosemionotus vogeli is described and redefined. These findings and search in the literature demonstrate that a rich vertebrate fauna existed in the sea of the Middle Muschelkalk; the contrary is accepted generally.  相似文献

A detailed stratigraphic section of the Lower Toarcian Posidonienschiefer of Schandelah near Braunschweig (Niedersachsen, West Germany) is presented, and a pterosaur pelvis from that locality referred to asCampylognathoides sp. is described. It is the first record of this genus in North West Germany. A restoration of the pelvis indicates a laterally, slightly upwardly directed orientation of the acetabula which does not support a bird-like bipedal locomotion of this pterosaur as has been suggested elsewhere.  相似文献

Galve (Teruel, Spain) is a town in the interior of a synclinal fold with Upper Jurassic marine limestones along its flanks, and, in its core, Upper Jurassic–Lower Cretaceous continental and shoreline sediments crop out. The core sediments cover an area about 8 km2, and contain a concentration of sites with footprints, bones, and eggshells of dinosaurs. The footprints are both shafts and natural casts. Some casts are attributed to stegosaurs (Deltapodus). The Deltapodus casts are characterized by features that allow us to make direct observations on the skin formed by polygonal scales, and ellipsoidal “hooves,” as well as deductions on the movement of the limbs during walking. According to the opinion of some authors, dinosaur footprints are indicators of the motion of their limbs and sometimes of the whole body. So far, results have been deduced from theropod, ornithopod, and sauropod footprints. This article shows the results obtained from analis of the aforementioned Deltapodus casts, i.e., forelimb movement similar to that of the forelimbs of sauropods, and the rigid structure of the autopodial part of the hind limb.  相似文献

The first calcitic thecas of edrioasteroids from the Rheinisches Schiefergebirge are described:Timeischytes leunisseni n. sp.,Timeischytes prescheri n. sp. andRhenopyrgus sp. are from the Middle Devonian of the Eifel Hills. The morphological features ofTimeischytes lead to the assumption that in this genus paedomorphosis has been a long-lasting process.  相似文献

De Janeiro de 1962 até Dezembro de 1965, 6141 caç[otilde]es pertencentes a 19 espécies foram examinados (tabela 2). No trabalho presente, os animais são tratados de acôrdo com a sua freqüência. Foram pescados nas proximidades de Cananéia (Lat. 2 5°S, Long. 47° 52' O), em 4–10 m de profundidade, sôbre fundo lodoso. Carcharhinus maculipinnis e Aprionodon isodon são novos para 0 Brasil; Ginglymostoma cirratum, Carcharhinus milberti e C. porosus, novos para o Sul do Brasil, onde o último é até comum, apesar de ser conhecido, até agora, sòmente do extrêmo Norte do Brasil. Mais 5 espécies (veja Parte Gérai, 30 parágrafo), de 20–25 m de profundidade, foram vistas no mercado local. Carch. taurus, de fraca reprodutibilidade e alto valor comercial, parece estar, de certo modo, sobrepescado. Geralmente, a quantidade de caç[otilde]es depende das variaç[otilde]es das condiç[otilde]es no mar que por sua vez influenciam os cardumes dos peixes apresados pelos caç[otilde]es. Por isso, os resultados das nossas pescas variam muito (tabela 1), mas, os meses de Junho a Agôsto foram improdutivos em todos os anos. O tamanho dos caç[otilde]es difere de acôrdo com a espécie, a idade e o sexo (tabela 3). A época da reprodução, do acasalamento e da gestação foi observada nas espécies ocorrentes regular e abundantemente, ou inferida (tabela 4). A relação entre pêso e comprimento dos caç[otilde]es e dos figados encontra‐se indicada na tabela 5.  相似文献

From rocks of Westphalian D age of Ibbenbueren in Westphalia/W-Germany a new taxon of the Omaliidae Handlirsch, 1906 -Kelleropteron kaelberbergense n. g., n. sp. — is described. It is represented by only one wing. The new genus is characterized by the following features: the subcosta ends on the costa; the radius is very prominent and runs far distantly from the anterior border of the wing proximally; the branches of the sector radii and the medialis are directed distally, not posteriorly; a connective vein between medialis and sector radii is present; the cross-veins are relatively dense and irregularly branched. The Omaliidae are redefined, the relationships of their genera are discussed. The genera are arranged in 3 groups (Fig. 1). In theHeterologies-group - as in the Paoliidae — the subcosta ends on the radius; in theCacurgus — group the subcosta ends on the costa, a connective vein between medialis and sector radii is not present; in theOmalia- group the subcosta also ends on the costa, but a connective vein between medialis and sector radii has evolved.Kelleropteron is a member of the last group, differing fromOmalia above all by its denser, more irregularly arranged cross-veins. The Omaliidae are confined stratigraphically to the Westphalian and geographically to the EuropeanNorthamerican region. They apparently are descendants of the Paoliidae Handlirsch, 1906. In both families a connective vein between medialis and cubitus is present, and the anterior branch of the medialis is lost. The most important difference between them is seen in the cross-veins: within the Paoliidae they are very dense, similar to the archedictyon of the Palaeodictyoptera, but within the Omaliidae they are more widemeshed and more prominent.  相似文献
