While several other titanosaurs relied on their sheer size to dissuade predators from attacking them, an analysis of a collection of incomplete fossil skeletons of Saltasaurus suggests that the species employed a different defensive strategy.

The dig revealed one of the most-complete titanosaur skeletons discovered thus far. Estimates that are particularly uncertain due to very fragmentary or lost material are preceded by a question mark.

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 Anatomy and Phylogenetic Relationships of Antetonitrus Ingenipes (Sauropodiformes, Dinosauria): Implications for the Origins of Sauropoda
    THE ANATOMY AND PHYLOGENETIC RELATIONSHIPS OF ANTETONITRUS INGENIPES (SAUROPODIFORMES, DINOSAURIA): IMPLICATIONS FOR THE ORIGINS OF SAUROPODA Blair McPhee A dissertation submitted to the Faculty of Science, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2013 i ii ABSTRACT A thorough description and cladistic analysis of the Antetonitrus ingenipes type material sheds further light on the stepwise acquisition of sauropodan traits just prior to the Triassic/Jurassic boundary. Although the forelimb of Antetonitrus and other closely related sauropododomorph taxa retains the plesiomorphic morphology typical of a mobile grasping structure, the changes in the weight-bearing dynamics of both the musculature and the architecture of the hindlimb document the progressive shift towards a sauropodan form of graviportal locomotion. Nonetheless, the presence of hypertrophied muscle attachment sites in Antetonitrus suggests the retention of an intermediary form of facultative bipedality. The term Sauropodiformes is adopted here and given a novel definition intended to capture those transitional sauropodomorph taxa occupying a contiguous position on the pectinate line towards Sauropoda. The early record of sauropod diversification and evolution is re- examined in light of the paraphyletic consensus that has emerged regarding the ‘Prosauropoda’ in recent years. iii ACKNOWLEDGEMENTS First, I would like to express sincere gratitude to Adam Yates for providing me with the opportunity to do ‘real’ palaeontology, and also for gladly sharing his considerable knowledge on sauropodomorph osteology and phylogenetics. This project would not have been possible without the continued (and continual) support (both emotionally and financially) of my parents, Alf and Glenda McPhee – Thank you.

  • Ancient Crocodile Relative Likely Food Source for Titanoboa 2 February 2010, by Bill Kanapaux
    Ancient crocodile relative likely food source for Titanoboa 2 February 2010, by Bill Kanapaux "We're starting to flesh out the fauna that we have from there," said lead author Alex Hastings, a graduate student at the Florida Museum and UF's department of geological sciences. Specimens used in the study show the new species, named Cerrejonisuchus improcerus, grew only 6 to 7 feet long, making it easy prey for Titanoboa.

  • The Fragile Legacy of Amphicoelias Fragillimus (Dinosauria: Sauropoda; Morrison Formation – Latest Jurassic)
    Volumina Jurassica, 2014, Xii (2): 211–220 DOI: 10.5604/17313708 .1130144 The fragile legacy of Amphicoelias fragillimus (Dinosauria: Sauropoda; Morrison Formation – latest Jurassic) D. Cary WOODRUFF1,2, John R. FOSTER3 Key words: Amphicoelias fragillimus, E.D. Cope, sauropod, gigantism. Abstract. In the summer of 1878, American paleontologist Edward Drinker Cope published the discovery of a sauropod dinosaur that he named Amphicoelias fragillimus. What distinguishes A. fragillimus in the annals of paleontology is the immense magnitude of the skeletal material. The single incomplete dorsal vertebra as reported by Cope was a meter and a half in height, which when fully reconstructed, would make A. fragillimus the largest vertebrate ever. After this initial description Cope never mentioned A. fragillimus in any of his sci- entific works for the remainder of his life. More than four decades after its description, a scientific survey at the American Museum of Natural History dedicated to the sauropods collected by Cope failed to locate the remains or whereabouts of A. fragillimus. For nearly a cen- tury the remains have yet to resurface. The enormous size of the specimen has generally been accepted despite being well beyond the size of even the largest sauropods known from verifiable fossil material (e.g. Argentinosaurus). By deciphering the ontogenetic change of Diplodocoidea vertebrae, the science of gigantism, and Cope’s own mannerisms, we conclude that the reported size of A. fragillimus is most likely an extreme over-estimation.

  • Osteology of Saltasaurus Loricatus
    OSTEOLOGY OF SALTASAURUS LORICATUS (Sauropoda-Titanosauridae) of the Upper Cretaceous of Northwest Argentina* Jaime E. Powell Faculty of Natural Sciences National University of Tucumán Argentina Translated by: Nancie M. Ecker Virginia Tidwell Denver Museum of Natural History ABSTRACT * Original citation: Powell, J. E. 1992. Osteologia de Saltasaurus loricatus (Sauropoda - Titanosauridae) del Cretácico Superior del noroeste Argentino. In J. L. Sanz and A. D. Buscalioni (eds.), Los Dinosaurios y Su Entorno Biotico: Actas del Segundo Curso de Paleontologia in Cuenca. Institutio "Juan de Valdes", Cuenca, Argentina:165-230. The anatomy of the titanosaurid dinosaur Saltasaurus loricatus Bonaparte and Powell is described, based upon a great number of bones found in the Lecho Formation, Southern Salta Province, Northwestern Argentina. This dinosaur was a medium-sized sauropod with short and robust limbs, characterized by a dermal armor integrated by scutes and small rounded intradermal ossicles. The skull has a long and recurved paroccipital process considered as a synapomorphy for the Titanosauridae. As in all titanosaurids, Saltasaurus loricatus has cancellous bone in sacral and presacral centra, but this condition is also present in the anterior caudals. A new subfamily is proposed: Saltasaurinae. INTRODUCTION The family Titanosauridae includes sauropod dinosaurs from medium size to gigantic, constituting the most conspicuous group of large herbivores in the Upper Cretaceous in South America. Its presence on the subcontinent was recognized by Lydekker (1893) on the basis of remains originating in Patagonia, Argentina (provinces of Neuquen and Chubut). Huene (1929) later completed an important study about the dinosaurs of the Upper Cretaceous in South America, devoting himself especially to the analysis of titanosaurs.
