A new basal testudinoid turtle (Testudinoidea: “Lindholmemydidae”) from the Upper Paleocene of Mongolia

A new genus and species of a basal testudinoid turtle of the family “Lindholmemydidae,” Paramongolemys khosatzkyi gen. et sp. nov., is described based on shell material from the Naranbulak Formation (Upper Paleocene) of the Naran Bulak and Khaychin-Ula IE localities (Mongolia). Material of this species includes some specimens previously described as Mongolemys tatarinovi.     

New jewel beetles (Coleoptera: Buprestidae) from the Cretaceous of Russia,Kazakhstan, and Mongolia

A new jewel beetle genus, with one species (Cretofrontolina kzyldzharica gen. et sp. nov.) from the Upper Cretaceous of Kazakhstan is described based on a body; and three new species of the formal genus Metabuprestium are described based on isolated elytra: Metabuprestium sibiricum sp. nov. and M. arkagalense sp. nov. come from the Arkagala locality (Upper Cretaceous of Russia) and M. ichbogdense sp. nov. is from the Shar Tologoi locality (Lower Cretaceous of Mongolia).     

Sur quelques sélaciens nouveauxdu Crétacé supérieur de Bolivie: Amérique du Sud

The locality of Torotoro (Puca Group, Upper Cretaceous of Bolivia) has yielded a small shark-fauna including a new genus and five new species: Pucabatis hoffstetteri nov. gen., nov. sp., Ischyrhiza hartenbergeri nov. sp., Dasyatis branisai nov. sp., D. molinoensis nov. sp. et D. schaefferi nov. sp. The genus Pucapristis, previously described on rostral teeth, is represented by numerous oral teeth unknown until this day. The occurence of the genus Schizorhiza, already pointed out, allows to attribute the El Molino formation to maestrichtian.

Margin feeding damage on the leaves of conifers and ginkgoales from the Mesozoic of Transbaikalia

A new approach to the formal classification of arthropod margin feeding plant damage is proposed. Several types of margin feeding traces on the leaves of Pityophyllum sp. and Ginkgoites sp. from the Upper Jurassic-Lower Cretaceous Chernovskie Kopi locality, Transbaikalia, are described as five new species in the genus Pinovulnus gen. nov.     

Fossil wood of Piceoxylon burejense sp. nov. (Pinaceae) from the Upper Cretaceous of Zeya-Bureya Basin, Amur Region (Russian Far East)

A new species, Piceoxylon burejense sp. nov. (Pinaceae), is described from the Middle Maastrichtian (Upper Cretaceous) of the Zeya-Bureya Basin, Amur Region (Russian Far East) based on the fossil wood anatomy. The new species is characterized by a combination of anatomical wood features of the modern genera Picea and Larix. The fossil wood of Pinaceae was found in the Cretaceous deposits of the Amur Region for the first time.     

On Mulleripollis gen. nov., a pollen tetrad from the upper cretaceous of the Bengal Basin,West Bengal,India

A tetrahedral tetrad of tricolpate, striate pollen from the Upper Cretaceous subcrop sediments of the Bengal Basin has been described under a new generic name, Mulleripollis gen. nov., with the type species Mulleripollis bolpurensis gen. et sp. nov. It has been noticed that this pollen tetrad is restricted to the Upper Cretaceous Bengal Palynological Zone, which is stratigraphically significant. The natural affinity of the pollen could not be established.     

Revidierte Systematik der Ostracoden im Oberjura und der basalen Kreide Ostdeutschlands

The Upper Jurassic and basal Cretaceous ostracod faunas of Northeastern Germany, which have not been sufficiently investigated and documented yet, are revised. The fauna, documented by stratigraphical tables and SEM-pictures, consists of 116 species from 36 genera, two species of which are new:Galliaecytheridea wienholzae n. sp. andRasthalmocythere keuppi n. sp. The biostratigraphical ränge of the taxa extends from the Oxfordian to the early Berriasian. A palaeobiogeographical correlation with the ostracod faunas of Northwestern Germany reveals close relationships between both areas concerning the stratigraphical range and assemblage of the fauna.     

The first scorpion fossil from the Cretaceous amber of Myanmar (Burma). New implications for the phylogeny of Buthoidea

A specimen belonging to a new genus and species of fossil scorpion, Palaeoburmesebuthus grimaldii gen. n., sp. n., is described from the Upper Cretaceous amber of Myanmar (Burma). This is the first scorpion to have been found and described from Burmese amber (± 90 Myr). The new genus and species are unquestionable buthoid elements but they are assigned to an incertae familiae until further material may be available for study. To cite this article: W.R. Lourenço, C. R. Palevol 1 (2002) 97–101.     

A new leptoceratopsid (Ornithischia: Ceratopsia) from the Upper Cretaceous of Shandong, China and its implications for neoceratopsian evolution

Background

The ceratopsians represent one of the last dinosaurian radiations. Traditionally the only universally accepted speciose clade within the group was the Ceratopsidae. However, recent discoveries and phylogenetic analyses have led to the recognition of a new speciose clade, the Leptoceratopsidae, which is predominantly known from the Upper Cretaceous of North America.

Methodology/Principal Findings

Here we report a new leptoceratopsid taxon, Zhuchengceratops inexpectus gen. et sp. nov., based on a partial, articulated skeleton recovered from the Upper Cretaceous Wangshi Group of Zhucheng, Shandong Province, China. Although Zhuchengceratops is significantly different from other known leptoceratopsids, it is recovered as a derived member of the group by our phylogenetic analysis. Furthermore, Zhuchengceratops exhibits several features previously unknown in leptoceratopsids but seen in ceratopsids and their close relatives, suggesting that the distribution of morphological features within ceratopsians is more complex than previously realized.

Conclusion/Significance

The discovery of Zhuchengceratops increases both the taxonomic diversity and the morphological disparity of the Leptoceratopsidae, providing further support for the hypothesis that this clade represents a successful radiation of horned dinosaurs in parallel with the Ceratopsidae in the Late Cretaceous. This documents a surprising case of the coexistence and radiation of two closely-related lineages with contrasting suites of jaw and dental features that probably reflect adaptation to different food resources.     

New Ichneumonidae (Hymenoptera) from the Upper Cretaceous ambers of the Taimyr Peninsula

Two new genera and four new species of Ichneumonidae are described from the Upper Cretaceous ambers of the Taimyr Peninsula: Agapia sukatchevae gen. et sp. nov., Agapteron popovi gen. et sp. nov., Eubaeus abdominalis sp. nov., and Urotryphon baikurensis sp. nov. New detailed diagnoses are provided for the genera Urotryphon and Eubaeus. The genera Catachora, Urotryphon, and Eubaeus, previously placed in the subfamily Tryphoninae, are transferred to the subfamily Labenopimplinae, as well as the new genera Agapia and Agapteron. Possible causes of the miniaturization in ichneumonid wasps in the Cretaceous are discussed.     

The serphitid wasps (Hymenoptera: Proctotrupo‐morpha: Serphitoidea) of Canadian Cretaceous amber

Five new species and one new genus of Serphitidae microhymenoptera are described from Upper Cretaceous (Campanian) amber originating at the Grassy Lake locality in Alberta, Canada. New taxa include Serphites hynemani sp.n. , Serphites bruesi sp.n. , Serphites kuzminae sp.n. , Serphites pygmaeus sp.n. and Jubaserphites ethani gen. et sp.n. Topotype material for the type species of Serphites, Serphites paradoxus Brues is re‐illustrated and redescribed in greater detail, clarifying the characteristics of the species for comparison with the numerous serphitids that have been described subsequent to the work of Brues. We provide the first comprehensive report of known serphitid specimens in Canadian amber, draw comparisons with taxa in other Cretaceous deposits, and comment upon the palaeoecological connotations of the relatively diverse and morphologically disparate Canadian serphitid assemblage.     

Palynology of the Dockum group (Upper Triassic), Texas,U.S.A.

Rectogerochammina eugubina nov. gen., nov. sp., a new agglutinated foraminifer from the Upper Cretaceous of Gubbio, Italy

We describe the new agglutinated foraminiferal genus and species Rectogerochammina eugubina nov. gen., nov. sp. from the Upper Cretaceous Scaglia Rossa Formation of the Umbria-Marche Basin in Italy. The genus differs from Gerochammina (Neagu, 1990) in the presence of a terminal uniserial part.     

Bryozoaires du Crétacé supérieur trouvés dans les résidusdu remplissage d'une fente karstique dans les Gorges du Nant (Vercors)

33 species of Upper Cretaceous silicified bryozoansfound by A. Arnaud-Vanneau and H. Arnaud (Grenoble) within a crevice filled with residual clay, have been studied. Most of the species are known from the Senonian (Coniacian — Santonian) of the Anglo-Paris Basin. The faunal relations with the Upper Cretaceous Bryozoa of the Provence, of the Aquitain Basin or the Alpine regions (Austrian Alps) are less significant. Decurella? arnaudae nov. sp. and Onychocella subpalpigera nov. sp. are described.

Rich radiolarian associations are investigated. They include nine new species from the Upper Cretaceous (Coniacian-Santonian) metal-bearing beds of the Perapedhia Formation of southern Cyprus: Dorypyle concinna sp. nov., Gongylothorax mangaleniensis sp. nov., Heliocryptocapsa macroporus sp. nov., H. perapediensis sp. nov., Mita guttiformis sp. nov., Pseudoeucyrtis belogorskensis sp. nov., P. cypricus sp. nov., Rhopalosyringium mangaleniense sp. nov., and Sandovalella trihedra sp. nov.     

Nouvelles espèces de dasycladales du crétacé inférieur de provence (S.E. France)

In the Lower Cretaceous of Provence Cylindroporella faronensis n. sp. and Cylindroporella massiliana n. sp. represent small size species with a limited number of branches. The former ranges from the Middle (or Lower p.p. ?) Berriasian to the Lower Valanginian, the latter is found in the Lower Hauterivian, but could appear earlier in other regions. Clypeina isabellae n. sp. is also a small size form with a fibrous, yellowish microstructure, close to Clypeina sulcata, it is restricted to the Middle (or Lower p.p. ?) and Upper Berriasian. Besides their biostratigraphic and palaeobiogeographic potential value this material from Provence is also interesting from an evolutionary point of view. At generic levels it shows distinctive patterns relatively to the “Cope law”.     

Nouveaux brachiopodes Chonetacea du Dévonien de la Cordillère cantabrique (Nord-Ouest d e l'Espagne)

The study of Chonetacean Brachiopods from Cantabrian Mountains allows to recognize several new taxa restricted to this area. A new genus and seven species of which six are new, are described in this paper; their vertical distribution is from Gedinnian to Upper Givetian: Chonetes bediae n. sp., Chonetes? kerforneiRenaud, 1942, Plebejochonetes coliensis n. sp., Plebejochonetes moniellensis n. sp., Luanquella cantabriensis n. g., n. sp., Plicanoplia sotoi n. sp. et Longispina truyolsi. n. sp. The species kerfornei, from the Middle Devonian of Armorican Massif is cited here for the first time from Spain.     

Phu Din Daeng,a new Early Cretaceous vertebrate locality on the Khorat Plateau,NE Thailand

In this paper, we report on a new Early Cretaceous vertebrate locality, Phu Din Daeng, in Nakhon Phanom Province, NE Thailand. The Phu Din Daeng site has yielded a diverse vertebrate assemblage, including sharks (Heteroptychodus steinmanni), bony fishes (Pycnodontiformes; Sinamiidae cf. Siamamia and ?Vidalamiinae, and Ginglymodi), adocid turtles, indeterminate neosuchian crocodiles, pterosaurs and dinosaurs (spinosaurids and indeterminate theropods). A new adocid turtle, Protoshachemys rubra n. g. n. sp. is described on the basis of shell material. Field investigations on the geology and comparisons with other vertebrate faunas place Phu Din Daeng in the Sao Khua Formation (Barremian) of the Khorat Group.
