The latitudinal trajectories of selected Gondwana dinosaur localities were traced throughtime in order to evaluate their movement through climate zones relative to those in which they originally formed. The dispersal of fauna during the breakup of Gondwana may have been facilitated by the presence of offshelf islands forming landspans (sensu Iturralde-Vinent and MacPhee) in the Equatorial Atlantic Gateway and elsewhere. Key words: biogeography, dinosaur, Gondwana, latitude. INTRODUCTION Ark as a segment of continental crust with its biota, In 1973 Malcolm C.

    Basal abelisaurid and carcharodontosaurid theropods from the Lower Cretaceous Elrhaz Formation of Niger PAUL C. SERENO and STEPHEN L. BRUSATTE Sereno, P.C. and Brusatte, S.L. 2008. Basal abelisaurid and carcharodontosaurid theropods from the Lower Cretaceous Elrhaz Formation of Niger. Acta Palaeontologica Polonica 53 (1): 15–46. We report the discovery of basal abelisaurid and carcharodontosaurid theropods from the mid Cretaceous (Aptian– Albian, ca. 112 Ma) Elrhaz Formation of the Niger Republic. The abelisaurid, Kryptops palaios gen. et sp. nov., is repre− sented by a single individual preserving the maxilla, pelvic girdle, vertebrae and ribs. Several features, including a maxilla textured externally by impressed vascular grooves and a narrow antorbital fossa, clearly place Kryptops palaios within Abelisauridae as its oldest known member. The carcharodontosaurid, Eocarcharia dinops gen. et sp. nov., is repre− sented by several cranial bones and isolated teeth. Phylogenetic analysis places it as a basal carcharodontosaurid, similar to Acrocanthosaurus and less derived than Carcharodontosaurus and Giganotosaurus. The discovery of these taxa sug− gests that large body size and many of the derived cranial features of abelisaurids and carcharodontosaurids had already evolved by the mid Cretaceous. The presence of a close relative of the North American genus Acrocanthosaurus on Af− rica suggests that carcharodontosaurids had already achieved a trans−Tethyan distribution by the mid Cretaceous.

Today it has a wide 10 distribution across the northern Sahara where it has enormous socio-economic importance as a major 11 freshwater aquifer. During the Early Cretaceous major north-south trending basement structures were 12 reactivated in response to renewed Atlantic rifting and in Algeria, faults along the El Biod-Hassi 13 Messaourd Ridge appear to have been particularly important in controlling thickness patterns of the 14 Lower Cretaceous Continental Intercalaire. Subsurface data from the Krechba gas field in Central Algeria 15 shows that the Lower Cretaceous stratigraphy is subdivided into two clear parts. The lower part (here 16 termed the In Salah Formation) is a 200 m thick succession of alluvial deposits with large meandering 17 channels, clearly shown in 3D seismic, and waterlogged flood basins indicated by lignites and gleyed, 18 pedogenic mudstones. The overlying Krechba Formation is a 500 m thick succession of quartz- 19 dominated sands and sandstones whose microstructure indicates an aeolian origin, confirming earlier 20 observations from outcrop.

Rivadavia 1917 - Cdad. de Buenos Aires, Argentina (Received 28 November 2008; revised 09 July 2009; accepted 14 July 2009) ABSTRACT The oldest unequivocal records of Dinosauria were unearthed from Late Triassic rocks (approximately 230 Ma) accumulated over extensional rift basins in southwestern Pangea. The better known of these are Herrerasaurus ischigualastensis, Pisanosaurus mertii, Eoraptor lunensis,andPanphagia protos from the Ischigualasto Formation, Argentina, and Staurikosaurus pricei and Saturnalia tupiniquim from the Santa Maria Formation, Brazil. No uncontroversial dinosaur body fossils are known from older strata, but the Middle Triassic origin of the lineage may be inferred from both the footprint record and its sister-group relation to Ladinian basal dinosauromorphs. These include the typical Marasuchus lilloensis, more basal forms such as Lagerpeton and Dromomeron, as well as silesaurids: a possibly monophyletic group composed of Mid-Late Triassic forms that may represent immediate sister taxa to dinosaurs. The first phylogenetic definition to fit the current understanding of Dinosauria as a node-based taxon solely composed of mutually exclusive Saurischia and Ornithischia was given as ‘‘all descendants of the most recent common ancestor of birds and Triceratops’’.

  • The Sauropodomorph Biostratigraphy of the Elliot Formation of Southern Africa: Tracking the Evolution of Sauropodomorpha Across the Triassic–Jurassic Boundary
    Editors' choice The sauropodomorph biostratigraphy of the Elliot Formation of southern Africa: Tracking the evolution of Sauropodomorpha across the Triassic–Jurassic boundary BLAIR W. MCPHEE, EMESE M. BORDY, LARA SCISCIO, and JONAH N. CHOINIERE McPhee, B.W., Bordy, E.M., Sciscio, L., and Choiniere, J.N. 2017. The sauropodomorph biostratigraphy of the Elliot Formation of southern Africa: Tracking the evolution of Sauropodomorpha across the Triassic–Jurassic boundary. Acta Palaeontologica Polonica 62 (3): 441–465. The latest Triassic is notable for coinciding with the dramatic decline of many previously dominant groups, followed by the rapid radiation of Dinosauria in the Early Jurassic. Among the most common terrestrial vertebrates from this time, sauropodomorph dinosaurs provide an important insight into the changing dynamics of the biota across the Triassic–Jurassic boundary. The Elliot Formation of South Africa and Lesotho preserves the richest assemblage of sauropodomorphs known from this age, and is a key index assemblage for biostratigraphic correlations with other simi- larly-aged global terrestrial deposits. Past assessments of Elliot Formation biostratigraphy were hampered by an overly simplistic biozonation scheme which divided it into a lower “Euskelosaurus” Range Zone and an upper Massospondylus Range Zone. Here we revise the zonation of the Elliot Formation by: (i) synthesizing the last three decades’ worth of fossil discoveries, taxonomic revision, and lithostratigraphic investigation; and (ii) systematically reappraising the strati- graphic provenance of important fossil locations. We then use our revised stratigraphic information in conjunction with phylogenetic character data to assess morphological disparity between Late Triassic and Early Jurassic sauropodomorph taxa. Our results demonstrate that the Early Jurassic upper Elliot Formation is considerably more taxonomically and morphologically diverse than previously thought.

  • A Troodontid Dinosaur from the Latest Cretaceous of India
    ARTICLE Received 14 Dec 2012 | Accepted 7 Mar 2013 | Published 16 Apr 2013 DOI: 10.1038/ncomms2716 A troodontid dinosaur from the latest Cretaceous of India A. Goswami1,2, G.V.R. Prasad3, O. Verma4, J.J. Flynn5 & R.B.J. Benson6 Troodontid dinosaurs share a close ancestry with birds and were distributed widely across Laurasia during the Cretaceous. Hundreds of occurrences of troodontid bones, and their highly distinctive teeth, are known from North America, Europe and Asia. Thus far, however, they remain unknown from Gondwanan landmasses. Here we report the discovery of a troodontid tooth from the uppermost Cretaceous Kallamedu Formation in the Cauvery Basin of South India. This is the first Gondwanan record for troodontids, extending their geographic range by nearly 10,000 km, and representing the first confirmed non-avian tetanuran dinosaur from the Indian subcontinent. This small-bodied maniraptoran dinosaur is an unexpected and distinctly ‘Laurasian’ component of an otherwise typical ‘Gondwanan’ tetrapod assemblage, including notosuchian crocodiles, abelisauroid dinosaurs and gondwanathere mammals. This discovery raises the question of whether troodontids dispersed to India from Laurasia in the Late Cretaceous, or whether a broader Gondwanan distribution of troodontids remains to be discovered. 1 Department of Genetics, Evolution, and Environment, University College London, London WC1E 6BT, UK. 2 Department of Earth Sciences, University College London, London WC1E 6BT, UK. 3 Department of Geology, Centre for Advanced Studies, University of Delhi, New Delhi 110 007, India. 4 Geology Discipline Group, School of Sciences, Indira Gandhi National Open University, New Delhi 110 068, India. 5 Division of Paleontology and Richard Gilder Graduate School, American Museum of Natural History, New York, New York 10024, USA.

The d18O values derived from inoceramids show a long-term increase from –3.2‰ in the Late Turonian to values between –0.8 and –1.8‰ in the Late Campanian. Assuming a constant oceanic d18Ovalue,an∼2‰ increase may reflect cooling of the shallow marine environment at Bentiaba by approximately 10°. Bentiaba values are offset by about +1‰ from published records for bathyal Inoceramus at Walvis Ridge. This offset in d18O values suggests a temperature difference of ∼5° between coastal and deeper water offshore Angola.

They are classically referred either to uniloc- ular parathuramminid foraminifera, algae incertae sedis or calcispheres (e.g., Bisphaera, Cribrosphaeroides, Uslo­ nia, Vermiporella myna, Irregularina). Due to their morphology and microstructural features, they are interpreted here as possibly belonging to Thaumatoporella PIA, a widespread Mesozoic-Early Cenozoic taxon of incertae sedis showing a remarkably high morphological variability. In analogy to Mesozoic thaumatoporellaceans, Bisphaera ma­ levkensis BIRINA is interpreted as the cyst (i.e.= resting) stage of forms ascribed to different genera, i.e., Cribro­ sphaeroides, Uslonia and Vermiporella (here: Vermiporella myna WRAY). Note that in the Mesozoic many taxa were also synonymized with Thaumatoporella: Polygonella ELLIOTT, Lithoporella elliotti (EMBERGER), Messopota­ mella DRAGASTAN et al., Vermiporella crisiae DRAGASTAN et al., Micritosphaera SCOTT. This new interpretation, based on material from the Devonian of W-Germany and the Czech Republic, leads to taxonomic reassessment as Thaumatoporella? malevkensis (BIRINA) nov.
