ABSTRACT: Fragmentary pterosaur remains from the Early Cretaceous Quebrada Monardes Formation of northern Chile are assigned to Ctenochasmatidae. Although not immediately referable to recognised genera, they differ from other South American occurrences of ctenochasmids and appear to share features of the dentition with Ctenochasma and Gnathosaurus from Late Jurassic deposits in Europe. A slightly spatulate rostrum may hint at affinities with the gnathosaurine ctenochasmatid Gnathosaurus. The presence of a possible gnathosaurine in South America is further evidence for a Hispanic corridor allowing faunal interchange between South America and Eurasia during the Late Jurassic and Early Cretaceous.

ABSTRACT: The Lower Cretaceous (Albian) locality of Pietraroia, Italy, has yielded a rich and diverse assemblage of fossil vertebrates, including at least one genus of rhynchocephalian (Derasmosaurus) and three named lizards (Chometokadmon, Costasaurus and Eichstaettisaurus). The type and only specimen of Chometokadmon is well-preserved but has never been comprehensively described or assessed. It was mistakenly classified as a sphenodontian for many years, but detailed reanalysis has shown that Chometokadmon is a squamate. The genus has a relatively unspecialised postcranial skeleton, but the skull is distinctive in having an elongated parietal, expanded squamosal, recurved teeth, and cranial osteoderms. A combination of cranial and postcranial characters (including separable cranial osteoderms, an elongate supratemporal, tooth and pubic morphology) supports a relationship with Anguimorpha, a hypothesis corroborated by cladistic analysis.

ABSTRACT: An isolated theropod dinosaur tooth discovered in 1984 near Nalut in northwestern Libya is the only known dinosaur record from the Aptian-Albian (Lower Cretaceous) Chicla Formation in the Jabal Nafusah region of the country. The tooth was re-examined in an effort to better ascertain its taxonomic affinities. A stepwise discriminant function analysis compared the Libyan tooth to the dentitions of 24 other theropods and classified the tooth with cranial material from the Late Cretaceous of India previously referred to the abelisaurid Indosuchus. The temporal and paleogeographic "distance" separating the Libyan specimen from "Indosuchus" indicates that the former cannot pertain to that genus. However, the results of the analysis and synapomorphies of Abelisauridae present on the Libyan crown indicate that it can be referred to the clade, thus contributing to the growing record of Abelisauridae in the Cretaceous of mainland Africa.

Ksepka, D.T., Bertelli, S., and Giannini, N.P. 2006. The phylogeny of the living and fossil Sphenisciformes (penguins). Cladistics 22(5):412-441. doi: 10.1111/j.1096-0031.2006.00116.x.

ABSTRACT: We present the first phylogenetic analysis of the Sphenisciformes that extensively samples fossil taxa. Combined analysis of 181 morphological characters and sequence fragments from mitochondrial and nuclear genes (12S, 16S, COI, cytochrome b, RAG-1) yields a largely resolved tree. Two species of the New Zealand Waimanu form a trichotomy with all other penguins in our result. The much discussed giant penguins Anthropornis and Pachydyptes are placed in two clades near the base of the tree. Stratigraphic and phylogenetic evidence suggest that some lineages of penguins attained very large body size rapidly and early in the clade's evolutionary history. The only fossil taxa that fall inside the crown clade Spheniscidae are fossil species assigned to the genus Spheniscus. Thus, extant penguin diversity is more accurately viewed as the product of a successful radiation of derived taxa than as an assemblage of survivors belonging to numerous lineages. The success of the Spheniscidae may be due to novel feeding adaptations and a more derived flipper apparatus. We offer a biogeographical scenario for penguins that incorporates fossil distributions and paleogeographic reconstructions of the Southern continent's positions. Our results do not support an expansion of the Spheniscidae from a cooling Continental Antarctica, but instead suggest those species that currently breed in that area are the descendants of colonizers from the Subantarctic. Many important divergence events in the clade Spheniscidae can instead be explained by dispersal along the paths of major ocean currents and the emergence of new islands due to tectonic events.

ABSTRACT: Therangospodus oncalensis is a Berriasian theropod ichnotaxon from the Cameros Basin (Soria Province, Spain). We discovered new trackways assigned to this ichnotaxon during cleaning and conservation works at the type locality (Fuentesalvo), enabling us to describe it more precisely. Therangospodus oncalensis was made by a medium-sized theropod dinosaur and is characterized by a single tapering pad on each toe, a rounded heel impression and a narrow trackway. In addition to having similar morphometric characteristics, most of the trackways at the Fuentesalvo site show comparable size and biometric features. This indicates that, in terms of size and age, a homogeneous population of a single theropod species could have produced these tracks. Moreover, the similar orientation (lying within a range of only 15°) and estimated speed suggested by most of the trackways, lend weight to the hypothesis that the trackmaker of Therangospodus oncalensis was able, at least at times, to move in structured packs displaying gregarious behaviour. Furthermore, this is the first structured pack of theropods to be described.

ABSTRACT: A lower jaw with multicusped teeth and a number of unique characteristics was discovered in an extensive exposure of the Upper Triassic Kössen Formation in the Northern Calcareous Alps. The ramus of the jaw is high and dominated by a row of large, oval foramina that lies parallel to the tooth row. In addition, the anterior portion of the dentary exhibits a large number of nutritive foramina and small pits, which might indicate an association with a soft tissue structure and/or the presence of a keratinous cover of that area during life. All elements of the jaw are thin-walled and hollow, possibly pneumatic. Two teeth are preserved within the dentary. One is tricuspid and the other bears four cusps. The teeth are noticeably small in comparison with the overall size of the ramus, being only one-third of the height of the ramus. The teeth show a strong similarity to those of the well-known basal pterosaur genus Eudimorphodon, whose jaw morphology, however, clearly differs from the specimen described in this study. The dentition and the pneumatic bone structure make an assignment to the Pterosauria plausible. Based on the great number of distinct morphological characters the specimen is described as Caviramus schesaplanensis gen. et sp. nov.

Senter, P. 2006. Forelimb function in Ornitholestes hermanni Osborn (Dinosauria, Theropoda). Palaeontology 49(5):1029-1034. doi: 10.1111/j.1475-4983.2006.00585.x.

ABSTRACT: Ornitholestes hermanni is a Late Jurassic theropod dinosaur from North America. This kinematic study of Ornitholestes uses manual manipulations of forelimb casts to determine range of motion. The manual phalanges of the O. hermanni holotype, previously unidentified, are here identified as phalanges I-1, I-2 (ungual), II-2 and II-3 (ungual). At all represented manual joints, hyperextensibility is small or absent, whereas flexion is strong, as in most other theropods. The elbow can be strongly flexed beyond a right angle. When data on range of forelimb motion in Ornitholestes are added to such data from other theropods, high elbow flexion is present in maniraptoriform coelurosaurs but not in basal theropods. Forelimb functions requiring strong elbow flexion (such as holding objects to the chest, or tucking the forearms in for their protection or to reduce wind resistance or heat loss) were therefore available to maniraptoriform coelurosaurs but not to basal theropods.
