Anne Mehlin, Sørensen , Finn, Surlyk
The tube-dwelling polychaete fauna from a late early Campanian rocky shore at Ivö Klack, southern Sweden, comprises 10 genera and 17 species, plus eight unidentified taxa. Spirorbins predominated on the shore and are considered opportunistic forms, well adapted to a wide range of environmental conditions. Factors controlling the settlement of polychaete larvae on different kinds of hard substrate are water energy, competition for space, and substrate size and stability. Four different kinds of hard substrate, a large gneiss boulder, an oyster valve, a pectinid valve, and a bone fragment are mapped in order to document species composition, density, orientation and...

The data presented here comprise Ryazanian–Valanginian carbon isotope ratios analyzed from fossil wood and belemnites from the shallow marine Boyarka River succession in Siberia. Additional belemnite carbon isotope ratios from the Izhma River succession (also Ryazanian–Valanginian) in Russia are also presented. The wood-derived and belemnite-derived isotope ratios are considered to primarily reflect changes in the terrestrial and marine carbon isotope reservoirs respectively. The δ13Ccarb and δ13Cwood records reveal a distinct mid-Valanginian positive carbon isotope excursion, with the initiation occurring near the Boreal Russian michalskii–polyptychus zone boundary, which is broadly time-equivalent Tethyan campylotoxus–verrucosum boundary. The Ryazanian–Valanginian δ13Ccarb values fluctuate between c....
Early Maastrichtian ammonites and nautiloids from Hrebenne, southeast Poland, and phenotypic plasticity of Acanthoscaphites tridens (Kner, 1848): A commentary

Marcin, Machalski
A recent attempt by Kin (2010, Cretaceous Research 31, 27-60) to reject dimorphism of a giant, early Maastrichtian scaphitid ammonite Acanthoscaphites tridens is not substantiated by the data presented by this author, which are of poor quality, and thus inadequate for testing biological hypotheses. Six “phenomorphic” classes proposed by Kin for the material of A. tridens from Hrebenne and other European localities, are purely typologic, arbitrary categories of no biological significance. Moreover, these categories are inadequately defined, even as for typologic standards. In contrast, a combination of size, relative height of the body chamber, shape of the umbilicus, and extent...

An integrated stratigraphic subdivision, on the basis of ammonites, belemnites, calpionellids and stable isotope ratios is proposed for the Lower Cretaceous carbonate succession of the Hárskút, Közöskút Ravine profile (HK-12), (Bakony Mts, Hungary). Abundant and diverse cephalopod assemblages occur in middle and late Berriasian Rosso Ammonitico facies, in a nearly complete sequence spanning the Tirnovella occitanica and Fauriella boissieri Zones. A new belemnite species, Duvalia hungarica, is described from this level. The overlying Lower Valanginian strata are condensed, but also yield rich assemblages of the Thurmanniceras pertransiens and Busnardoites campylotoxus Zones. The cephalopod fauna of the Late Valanginian Saynoceras verrucosum...
A new purported ankylosaur trackway in the Lower Cretaceous (lower Aptian) shallow-marine carbonate deposits of Puglia, southern Italy

The Apulian marine carbonate platform, a quite unusual environment for purported dry-land dwellers, has revealed a well-diversified ichnological record, especially for dinosaurs, including most high-rank groups namely sauropods, theropods, ankylosaurs and ornithopods. Recently, a small outcrop of Aptian age referred to the Calcare di Bari near Bisceglie (Bari) has yielded a new quadrupedal trackway that we attribute here to ankylosaurs. This new finding enhances the record of Cretaceous ankylosaur footprints from the Apulian carbonate Platform, previously known from another site near Bisceglie (early Aptian), from Borgo Celano (late Hauterivian-early Barremian), and from Altamura (upper Coniacian-early Santonian).
An early Campanian rocky shore at Ivö Klack, southern Sweden
Publication year: 2010
Source: Cretaceous Research, In Press, Accepted Manuscript, Available online 29 July 2010
Finn, Surlyk , Anne Mehlin, Sørensen
Well-exposed, ancient rocky shores are rare and the associated shelly faunas are normally strongly worn and fragmented due to erosion during both sea-level rise and fall. An early Campanian rocky shore with a rich fauna is preserved at Ivö Klack in the KristianstadBasin, southern Sweden. Ivö Klack is situated on the small, hilly islandof Ivö situated in lakeIvösjön with a lake level about 6 m above present-day sea level. The rocky shore was formed during a major late early Campanian transgression caused by a sea-level rise up to about 100 m above present sea level. An archipelago was formed along...
A new ichnogenus Skolichnus for Chondrites hoernesii Ettingshausen, 1863, a deep-sea radial trace fossil from the Upper Cretaceous of the Polish Flysch Carpathians: Its taxonomy and palaeoecological interpretation as a deep-tier chemichnion

Alfred, Uchman
A new ichnogenus Skolichnus is proposed for Chondrites hoernesii Ettingshausen, 1863 on the basis of the re-discovered type material and additional material from the collections and from the field work. All the material derives from the deep-sea Campanian-lower Maastrichtian Kropivnik Fucoid Marl, in the same region of the Skole Nappe in the Polish Flysch Carpathians. Skolichnus hoernesii (Ettingshausen, 1863) comb. n. is a radial trace fossil, composed of thin, simple, horizontal or sub-horizontal, thinly lined, numerous rays produced deeply in the sediment from a fixed position in a supposed shaft. Its deep position below the Chondrites tier suggests that its...

Upper Cenomanian pelagic sediments from the northern Alpine Helvetic fold-and-thrust belt (northern Tethyan margin) coeval with Oceanic Anoxic Event (OAE) 2 are characterized by the temporal persistence of micrite sedimentation and lack of organic carbon-rich layers. We studied an expanded section in the Chrummflueschlucht (east of Euthal, Switzerland), which encompasses the OAE 2 time interval. In order to identify the to identify the paleoceanographic and paleoenvironmental conditions during OAE 2 in this part of the northern Tethyan margin, and more specifically to trace eventual changes in nutrient levels and oxic conditions, we investigated the biostratigraphy (planktonic foraminifera), the bulk-rock mineralogy,...

Upper Cretaceous Lychnothamnus, Nitella and Tolypella (Charophyta) from Zampal, Argentina
Publication year: 2010

Eduardo A., Musacchio
Fossil gyrogonite and oosporangia remains belonging to the three extant Charoideae genera Lychnothamnus, Nitella and Tolypella are infrequent in pre-Tertiary sediments. The present record is striking owing to the geographical provenance of these microfossils at the same locality in west-central Argentina that formed part of the continent of Gondwana, which broke up during the Mesozoic. During the Turonian–Santonian, the pair Lychnothamnus-Nitella and the first record of Lychnothamnus (Pseudoharrisichara) comb. nov. are recognized as Gondwanan indicators. However, some associated widespread genera of Ostracoda warn of the possible coexistence of different controls on the biogeographical relationships in the region investigated. The present...

A new lizard from the early cretaceous of catalonia (Spain), and the mesozoic lizards of the iberian peninsula
Publication year: 2010

Arnau, Bolet , Susan E., Evans
The Early Cretaceous (late Berriasian-early Valanginan) locality of La Pedrera de Meià (Montsec, Catalonia, Spain) has yielded remains of at least two genera of lizards: Meyasaurus (including its synonym Ilerdaesaurus and possibly Rubiessaurus) and Eichstaettisaurus. A new lizard specimen is described and named here as Pedrerasaurus latifrontalis gen. et sp. nov., being sufficiently distinct from other known genera to warrant the erection of a new taxon. The results of phylogenetic analysis are equivocal but support the placement of the new genus within Scincogekkonomorpha. The new taxon resembles Meyasaurus, a genus widely distributed in the Lower Cretaceous of the Iberian Peninsula,...

An assemblage of amphibians and squamates from the Upper Maastrichtian of the Iberian Peninsula is described here for the first time. The material is disarticulated and comes from the Blasi 2 site of Huesca, Spain). The site is made up of grey marls belonging to the lower part of the Tremp Formation, and contains dinosaurs, crocodilians, testudines and Osteichthyes. The amphibians from Blasi 2 include one albanerpetontid (Albanerpeton aff. nexuosum) and two different anuran taxa: a discoglossid and a palaeobatrachid. The squamates comprise three lizards (two indeterminate lizards and one anguid) as well as an indeterminate snake (Alethinophidia). The vertebrate...
In situ spores of Asplenium and their implications for the evolution of the Aspleniaceae: a case study from the Lower Cretaceous Changcai Formation in eastern Jilin Province, China

Based on the gross morphology of leaves and fertile organs, including in situ spores, three species of Asplenium Linnaeus (A. changcaium Sun et Liu, A. popovii Samylina and A. tiefanum Deng) have been recognized for the first time in the Lower Cretaceous Changcai Formation in the Helong area (Yanbian), eastern Jilin Province, China. These are the only records of fossil Asplenium so far of an age that has been constrained between 125.1–116.8 Ma by isotopic dating, and might among the oldest in the world. This occurrence and earlier findings indicate that the divergence age of Asplenium from the other eupolypods...
Fossil vertebrate remains from Kut Island (Gulf of Thailand, Early Cretaceous)

The Mesozoic vertebrate fauna from Kut Island includes hybodont sharks (Hybodus sp., Isanodus paladeji, a new species of Heteroptychodus), actinopterygians (Semionotiformes indet., Lepidotes sp.), indeterminate turtles, goniopholidid crocodiles, cf. Theriosuchus sp. and theropod dinosaurs. The new hybodont species is also present in the Sao Khua Formation and maybe also in the Phu Kradung Formation on the Khorat Plateau in northeastern Thailand. The occurrence of both Isanodus paladeji and the new hybodont, together with heavily ornamented Semionotiformes teeth strongly suggest that this fauna is of the same age as the Sao Khua Formation one. Deposits from Kut Island are therefore younger...

The Cenomanian–Turonian (C–T) successions (Galala and Maghra el Hadida formations) exposed on the footwalls of the slopes of the Galala plateaus in the Wadi Araba area in the northern part of the Eastern Desert, Egypt yielded a fairly rich and moderately to well preserved ammonoid fauna. In total, 24 taxa have been identified, 17 of which are systematically described herein. Four genera (Thomelites, Euomphaloceras, Wrightoceras, Eubostrychoceras) and four species (Euomphaloceras septemseriatum, Vascoceras pioti, Fagesia cf. peroni, Wrightoceras munieri) are recorded for the first time from Egypt. In addition, the taxonomy of ammonoids previously reported from these successions has been re-evaluated....

The elemental content (major, trace and rare earth elements) of 35 Aptian–Albian limestone samples from the Mural Formation has been determined to provide information on depositional conditions and provenance. The limestones of the Mural Formation show large variations in terrigenous and carbonate contents (1.2 to 42.3% and 57.7 to 98.8% respectively). Small variations are observed in CaO concentrations in the Tuape Shale, Cerro La Puerta and Mesa Quemada members whereas large variations are found in the Cerro La Ceja, Los Coyotes and Cerro La Espina members. The majority of the limestones show high values of Th, Sc and Zr. Large...

Although caddisfly (Trichoptera) cases and adults are fairly abundant in the fossil record, fossils of the immature stages, particularly insights into the pupal stage, are exceedingly rare. Herein we report the discovery of a fossil caddisfly pupa, putatively of the family Vitimotauliidae, from Early Cretaceous deposits in northeastern China. This is the first fossil trichopteran pupa to have been described from China.
The Cretaceous Bagh Formation, India: a Gondwanan window onto Turonian shallow-water echinoid faunas
Publication year: 2010

Andrew B., Smith
The Bagh Formation of Madhya Pradesh (India) has yielded a rich echinoid fauna, but dating of this sequence has so far been controversial. The marine invertebrate faunas come from a condensed shallow-water succession of carbonates interrupted by several well-marked hardgrounds and depositional hiatuses. Eleven echinoid species (one of them new to science) are recognized and their distribution within the Bagh Formation is recorded. Five of these species have previously been recorded from strata in the Antantiloky region of Madagascar that are securely dated as late Turonian on the basis of associated ammonites. A further species is restricted to Turonian sediments...
Biostratigraphic significance of spinicaudatans from the Upper Cretaceous Nanxiong Group in Guangdong, South China

The spinicaudatan genus Tenuestheria was originally described from the Upper Cretaceous Lanxi Formation in Jinhua, Zhejiang Province, China. Its frequent occurrence in contemporaneous strata elsewhere makes it an important index fossil for correlating non-marine red beds in southern China. Its discovery in the Zhutian Formation of the Nanxiong Group makes it possible to correlate the formation more accurately with the Tenuestheria-bearing beds elsewhere. Previously the whole of the Nanxiong Group was correlated with Maastrichtian formations whereas now only the Zhenshui Formation is considered to be of this age. The Zhutian Formation, which underlies it, correlates with early Santonian–Campanian formations. The...
