  • D Inosaur Paleobiology
    Topics in Paleobiology The study of dinosaurs has been experiencing a remarkable renaissance over the past few decades. Scientifi c understanding of dinosaur anatomy, biology, and evolution has advanced to such a degree that paleontologists often know more about 100-million-year-old dinosaurs than many species of living organisms. This book provides a contemporary review of dinosaur science intended for students, researchers, and dinosaur enthusiasts. It reviews the latest knowledge on dinosaur anatomy and phylogeny, Brusatte how dinosaurs functioned as living animals, and the grand narrative of dinosaur evolution across the Mesozoic. A particular focus is on the fossil evidence and explicit methods that allow paleontologists to study dinosaurs in rigorous detail. Scientifi c knowledge of dinosaur biology and evolution is shifting fast, Dinosaur and this book aims to summarize current understanding of dinosaur science in a technical, but accessible, style, supplemented with vivid photographs and illustrations. Paleobiology Dinosaur The Topics in Paleobiology Series is published in collaboration with the Palaeontological Association, Paleobiology and is edited by Professor Mike Benton, University of Bristol. Stephen Brusatte is a vertebrate paleontologist and PhD student at Columbia University and the American Museum of Natural History. His research focuses on the anatomy, systematics, and evolution of fossil vertebrates, especially theropod dinosaurs. He is particularly interested in the origin of major groups such Stephen L. Brusatte as dinosaurs, birds, and mammals. Steve is the author of over 40 research papers and three books, and his work has been profi led in The New York Times, on BBC Television and NPR, and in many other press outlets.

  • A Huge Predatory Dinosaur, Built to Swim
    Science Now Discoveries from the world of science and medicine Spinosaurus: A huge predatory dinosaur, built to swim A digital skeletal reconstruction and transparent flesh outline of Spinosaurus aegyptiacus. The bones suggest this dinosaur was built to swim. Color codes show the origin of different parts of the digital skeletal model. (Model by Tyler Keillor, Lauren Conroy and Erin Fitzgerald, Ibrahim et al., Science/AAAS) By AMINA KHAN SEPTEMBER 11, 2014, 9:45 PM inosaurs ruled the land for millions of years. Now scientists have discovered a fearsome D species that could have wreaked havoc in its prehistoric waters. An unusual fossil whose parts were flung across two continents appears to be the first known semi-aquatic dinosaur, according to a report published Thursday by the journal Science. Measuring 9 feet longer than a Tyrannosaurus rex, the 95-million-year-old Spinosaurus aegyptiacus would have been the largest predatory dinosaur to walk the Earth. But it had several features that strongly suggest a life spent largely submerged in the water, including nostrils pushed toward the top of its skull and diagonally jutted teeth ideal for snapping up fish. “It was not a balancing, two-legged animal on land,” said study coauthor Paul Sereno, a paleontologist at the University of Chicago. “It would have been something very peculiar.” The differences between this Spinosaurus and other theropods are apparent from head to toe. Most theropods, like T. rex, ran on two powerful legs and had small, spindly arms. By contrast, the 50-foot-long Spinosaurus had muscular arms with blade-like claws that could have nabbed slippery prey, and shorter legs that were ill-equipped to walk on land.

You take your sandwich outside and you sit down to enjoy your lunch with a beautiful view of Montana’s Rocky Mountains. As you look up, you see what appears to be a bone sticking out of the side of a rock wall. That bone just so happens to be part of one of the best-preserved Tyrannosaurus rex fossils ever found. If you are Bob Harmon, a field crew chief of the Museum of the Rockies, ​ that is exactly what happened. In the year 2000 Bob Harmon discovered a 68 million-year-old fossil, which is now named “B-Rex” after him. Tyrannosaurus rex lived 65 to 70 million years ago, in what ​ is now the western parts of the United States. They were among the last of the large dinosaurs that lived on Earth. In certain rare cases, dinosaur bones were trapped in the Earth and were preserved until the present day, through a process called fossilization. Much of what we know about dinosaurs ​ ​ comes from the scientific study of the shape, appearance, composition, and location of fossils. Dinosaurs' bodies were made up of the same general types of biological building blocks seen in all animals, such as tissues, cells, and proteins.

Apesar desta grande distribuição temporal e geográfica, pouco se sabe sobre este grupo de dinossauros uma vez que a maior parte dos espécimes são incompletos. O clado Spinosauridae é dividido em Baryonychinae (Suchomimus + Baryonyx + Cristatosaurus) e Spinosaurinae (Spinosaurus+ Angaturama + Irritator). Apenas na África representantes destes dois clados foram encontrados. Uma possível explicação para a distribuição dos espinossaurídeos seria a dispersão de formas relacionadas a Baryonyx (o mais primitivo membro do grupo) da Europa para a África, onde surgiram os Spinosaurinae que posteriormente se distribuíram para a América do Sul. Palavras-chave: Dinosauria, Theropoda, Spinosauridae Abstract Spinosaur remains were collected in Africa, Europa, Asia and Brazil, coming from deposits with ages ranging from the Late Jurassic to the Late Cretaceous. Although having a wide distribution - both geographically and temporally - little is actually known about the group since most specimens are incomplete.

  • Triassic, Carnian) and the Early Evolution of Sauropodomorpha
    A Basal Sauropodomorph (Dinosauria: Saurischia) from the Ischigualasto Formation (Triassic, Carnian) and the Early Evolution of Sauropodomorpha Ricardo N. Martinez*, Oscar A. Alcober Museo de Ciencias Naturales, San Juan, Argentina Abstract Background: The earliest dinosaurs are from the early Late Triassic (Carnian) of South America. By the Carnian the main clades Saurischia and Ornithischia were already established, and the presence of the most primitive known sauropodomorph Saturnalia suggests also that Saurischia had already diverged into Theropoda and Sauropodomorpha. Knowledge of Carnian sauropodomorphs has been restricted to this single species. Methodology/Principal Findings: We describe a new small sauropodomorph dinosaur from the Ischigualsto Formation (Carnian) in northwest Argentina, Panphagia protos gen. et sp. nov., on the basis of a partial skeleton. The genus and species are characterized by an anteroposteriorly elongated fossa on the base of the anteroventral process of the nasal; wide lateral flange on the quadrate with a large foramen; deep groove on the lateral surface of the lower jaw surrounded by prominent dorsal and ventral ridges; bifurcated posteroventral process of the dentary; long retroarticular process transversally wider than the articular area for the quadrate; oval scars on the lateral surface of the posterior border of the centra of cervical vertebrae; distinct prominences on the neural arc of the anterior cervical vertebra; distal end of the scapular blade nearly three times wider than the neck; scapular blade with an expanded posterodistal corner; and medial lamina of brevis fossa twice as wide as the iliac spine. Conclusions/Significance: We regard Panphagia as the most basal sauropodomorph, which shares the following apomorphies with Saturnalia and more derived sauropodomorphs: basally constricted crowns; lanceolate crowns; teeth of the anterior quarter of the dentary higher than the others; and short posterolateral flange of distal tibia.

    Arquivos do Museu Nacional, Rio de Janeiro, v.62, n.3, p.309-320, jul./set.2004 ISSN 0365-4508 ON A SEQUENCE OF SACROCAUDAL THEROPOD DINOSAUR VERTEBRAE FROM THE LOWER CRETACEOUS SANTANA FORMATION, NORTHEASTERN BRAZIL 1 (With 14 figures) JONATHAS DE SOUZA BITTENCOURT 2, 3 ALEXANDER WILHELM ARMIN KELLNER 2, 4 ABSTRACT: Besides being rare, most theropod remains from fossil deposits of Brazil are incomplete. Up to date the Romualdo Member (Aptian/Albian) of the Santana Formation yielded six theropod specimens. To those we add the description of a sequence of three posterior sacral and six anterior caudal vertebrae with three chevrons (MN 4743-V). Differences between MN 4743-V and members of the major theropod clades such as Ceratosauria, Allosauroidea and Coelorusauria do not allow its assignment to one of those groups. Instead, MN 4743-V is referred to the Spinosauroidea (Spinosauridae plus Torvosauridae), based on the presence of three robust laminae below the transverse process of the anterior caudals, which delimit three fossae. The lack of paired processes on the chevrons suggest that within Spinosauroidea MN 4743-V is a member of the Spinosauridae. This is congruent with previous findings of spinosaurids in the Romualdo Member. MN 4743-V differs from the remaining specimens that present sacrocaudal elements indicating the co-existence of at least five theropod species in this deposit. Key words: Spinosauroidea, Dinosauria, Santana Formation, Lower Cretaceous, Brazil.

  • The Origin of the Dinosaurs El Origen De Los Dinosaurios
    III Jornadas Internacionales sobre Paleontología de Dinosaurios y su Entorno Salas de los Infantes, Burgos The Origin of the Dinosaurs El origen de los dinosaurios M. J. Benton Department of Earth Sciences, University of Bristol, Bristol, BS8 1RJ, U.K. e-mail: [email protected] Recibido el 15 de diciembre de 2004, aceptado el 18 de diciembre de 2005. Abstract The origin of the dinosaurs has long been debated. There are two aspects, phylogenetic and ecological-evo- lutionary. Much of the phylogenetic confusion has been resolved by cladistic analysis of basal archosaurs which shows that the dinosaurs originated as part of a major clade Avemetatarsalia/ Ornithodira. Closest relatives of the dinosaurs are small Mid Triassic bipedal animals such as Marasuchus from Argentina. The basal avemetatarsalian is Scleromochlus from the Late Triassic of Scotland. The classic ecological-evolutionary model for the initial radiation of the dinosaurs had been that they competed gradually through the Triassic with precursor groups, and eventually prevailed. More detailed study of the timing of events suggests that the dinosaurs radiated opportunistically in a two-phase model, with expansion of herbivorous sauropodomorphs fi rst in the early Norian, and expansion of large theropods and ornithischians in the Early and Mid Jurassic. Both expansion phases followed extinction events. Key words: Dinosaur, Triassic, origin, opportunism, Eoraptor, Herrerasaurus. Resumen El origen de los dinosaurios ha sido debatido durante mucho tiempo. Hay dos puntos de vista, el fi logenético y el ecológico-evolutivo. La mayor parte de la confusión fi logenética ha sido resuelta por análisis cladístico en arco- saurios basales.

  • Sauropod Dinosaur Remains from a New Early Jurassic Locality in the Central High Atlas of Morocco
    Sauropod dinosaur remains from a new Early Jurassic locality in the Central High Atlas of Morocco CECILY S.C. NICHOLL, PHILIP D. MANNION, and PAUL M. BARRETT Nicholl, C.S.C., Mannion, P.D., and Barrett, P.M. 2018. Sauropod dinosaur remains from a new Early Jurassic locality in the Central High Atlas of Morocco. Acta Palaeontologica Polonica 63 (1): 147–157. Despite being globally widespread and abundant throughout much of the Mesozoic, the early record of sauropod dinosaur evolution is extremely poor. As such, any new remains can provide significant additions to our understand- ing of this important radiation. Here, we describe two sauropod middle cervical vertebrae from a new Early Jurassic locality in the Haute Moulouya Basin, Central High Atlas of Morocco. The possession of opisthocoelous centra, a well-developed system of centrodiapophyseal laminae, and the higher elevation of the postzygapophyses relative to the prezygapophyses, all provide strong support for a placement within Sauropoda. Absence of pneumaticity indicates non-neosauropod affinities, and several other features, including a tubercle on the dorsal margin of the prezygapophyses and an anteriorly slanting neural spine, suggest close relationships with various basal eusauropods, such as the Middle Jurassic taxa Jobaria tiguidensis and Patagosaurus fariasi. Phylogenetic analyses also support a position close to the base of Eusauropoda. The vertebrae differ from the only other Early Jurassic African sauropod dinosaurs preserving overlapping remains (the Moroccan Tazoudasaurus naimi and South African Pulanesaura eocollum), as well as strati- graphically younger taxa, although we refrain from erecting a new taxon due to the limited nature of the material.
