  • Abelisauroidea and Carchardontosauridae (Theropoda, Dinosauria) in the Cretaceous of South America

Ángel Gallardo 470, C1405DJR, Buenos Aires, Argentina [email protected] Artigo recebido em 18/10/2004 e aceito para publicação em 31/08/2005 ABSTRACT: In this contribution an up-to-date list of abelisauroid ceratosaurians and carcharodontosaurid allosaurians recognized in South America is presented. Abelisauroids and carcharodontosaurids in South America show rich species diversity and a wide range of temporal and geographical distribution. At least eight formally described species of Abelisauroidea are recognized in Argen- tina and only one in Brazil; in contrast, only one species of Carcharodontosauridae is known for all South America. The fossil record of abelisauroids and carcharodontosaurids in South America shows a dominance of abelisauroids in the upper late Cretaceous, while the dominance of carcharodontosaurids as large predators was during the Cenomanian-Turonian. Although knowl- edge of the evolution of Abelisauroidea and Carcharodontasauridae in South America, as well as in the rest of Gondwana is still far for being complete, intensive explorations in recent years have provided greater insight into the composition of theropod faunas in the Cretaceous of Gondwana.

  • Theropod Dinosaurs from Argentina
    139 Theropod dinosaurs from Argentina Martín D. EZCURRA1 & Fernando E. NOVAS2 1CONICET, Sección Paleontología Vertebrados, Museo Argentino de Ciencias Naturales ‘Bernardino Rivadavia’, Av. Angel Gallardo 470, Buenos Aires, C1405DJR, Argentina. [email protected], Laboratorio de Anatomía Comparada y Evolución de los Vertebrados, Museo Argentino de Ciencias Naturales ‘Bernardino Rivadavia’, Av. Ángel Gallardo 470, Buenos Aires, C1405DJR, Argentina. [email protected] Abstract. Theropoda includes all the dinosaurs more closely related to birds than to sauropodomorphs (long-necked dinosaurs) and ornithischians (bird-hipped dinosaurs). The oldest members of the group are early Late Triassic in age, and non-avian theropods flourished during the rest of the Mesozoic until they vanished in the Cretaceous-Palaeogene mass extinction. Theropods radiated into two main lineages, Ceratosauria and Tetanurae, which are well represented in Cretaceous rocks from Argentina. Ceratosaurians are the most taxonomically diverse South American non-avian theropods, including small to large-sized species, such as the iconic horned dinosaur Carnotaurus. Argentinean tetanurans are represented by multiple lineages that include some of the largest carnivorous dinosaurs known worldwide (carcharodontosaurids), the enigmatic large-clawed megaraptorans, and small to medium-sized species very closely related to avialans (e.g. unenlagiids). The Argentinean non-avian theropod record has been and is crucial to understand the evolutionary and palaeobiogeographical

  • Isolated Theropod Teeth Associated with a Sauropod Skeleton from the Late Cretaceous Allen Formation of Río Negro, Patagonia, Argentina
    Isolated theropod teeth associated with a sauropod skeleton from the Late Cretaceous Allen Formation of Río Negro, Patagonia, Argentina JORGE G. MESO, CHRISTOPHE HENDRICKX, MATTIA A. BAIANO, JUAN I. CANALE, LEONARDO SALGADO, and IGNACIO DÍAZ-MARTÍNEZ Meso, J.G., Hendrickx, C., Baiano, M.A., Canale, J.I., Salgado, L., and Díaz-Martínez, I. 2021. Isolated theropod teeth associated with a sauropod skeleton from the Late Cretaceous Allen Formation of Río Negro, Patagonia, Argentina. Acta Palaeontologica Polonica 66 (2): 409–423. The discovery of theropod shed teeth associated with sauropod remains is relatively common in Cretaceous deposits of Patagonia. However, only a handful of studies have thoroughly explored the phylogenetic affinities of the theropod dental material. Here, we describe and identify twelve theropod shed teeth associated with a partially complete skeleton of a titanosaur sauropod from the Allen Formation (middle Campanian–lower Maastrichtian; Upper Cretaceous) of Paso Córdoba, Río Negro, Argentina. Using three methods, namely a cladistic analysis performed on a dentition-based data matrix, and a discriminant and cluster analyses conducted on a large dataset of theropod teeth measurements, we identify three dental morphotypes which are confidently referred to abelisaurid theropods. Whether the morphotypes represent different abelisaurid subclades or different positional entities within the jaw of the same abelisaurid species, is unknown. Such an identification, nevertheless, provides additional evidence of abelisaurids feeding on sauropod carcasses. This study highlights the importance of using combined qualitative and quantitative methodologies to identify isolated thero- pod teeth, especially those that can provide direct information on feeding ecology. Key words: Dinosauria, Abelisauridae, shed teeth, morphotypes, Cretaceous, Patagonia.

Basement inheritance and Foreland basin progressive shallowing of an east-dipping subducting slab are important mechanisms of foreland partitioning, as Provenance dictated by the preexisting (pre-Andean) structural architecture and forelandward (eastward) advance of Late U-Pb geochronology Cretaceous arc magmatism. Previously recognized growth strata help define the timing of fold-thrust belt Hf isotopes shortening and retroarc basement-involved uplift, but the precise consequences for sediment routing remain poorly understood, with uncertainties in patterns of basin evolution before, during, and after shallowing and resteepening of the subducting slab.

  • The Phylogeny of Ceratosauria (Dinosauria: Theropoda)
    Journal of Systematic Palaeontology 6 (2): 183–236 Issued 23 May 2008 doi:10.1017/S1477201907002246 Printed in the United Kingdom C The Natural History Museum The Phylogeny of Ceratosauria (Dinosauria: Theropoda) Matthew T. Carrano∗ Department of Paleobiology, National Museum of Natural History, Smithsonian Institution, Washington, DC 20560 USA Scott D. Sampson Department of Geology & Geophysics and Utah Museum of Natural History, University of Utah, Salt Lake City, UT 84112 USA SYNOPSIS Recent discoveries and analyses have drawn increased attention to Ceratosauria, a taxo- nomically and morphologically diverse group of basal theropods. By the time of its first appearance in the Late Jurassic, the group was probably globally distributed. This pattern eventually gave way to a primarily Gondwanan distribution by the Late Cretaceous. Ceratosaurs are one of several focal groups for studies of Cretaceous palaeobiogeography and their often bizarre morphological develop- ments highlight their distinctiveness. Unfortunately, lack of phylogenetic resolution, shifting views of which taxa fall within Ceratosauria and minimal overlap in coverage between systematic studies, have made it difficult to explicate any of these important evolutionary patterns. Although many taxa are fragmentary, an increase in new, more complete forms has clarified much of ceratosaur anatomy, allowed the identification of additional materials and increased our ability to compare specimens and taxa. We studied nearly 40 ceratosaurs from the Late Jurassic–Late Cretaceous of North and South America, Europe, Africa, India and Madagascar, ultimately selecting 18 for a new cladistic analysis. The results suggest that Elaphrosaurus and its relatives are the most basal ceratosaurs, followed by Ceratosaurus and Noasauridae + Abelisauridae (= Abelisauroidea).

Reappraisal of Austrosaurus mckillopi 11 Longman, 1933 from the Allaru Mudstone of Queensland, Australia’s first named Cretaceous 12 sauropod dinosaur. Alcheringa XX, XX–XX. ISSN ###. 13 14 Austrosaurus mckillopi Longman, 1933 was the first Cretaceous sauropod reported from 15 Australia, and the first Cretaceous dinosaur reported from Queensland (northeast Australia). 16 This sauropod taxon was established on the basis of several fragmentary presacral vertebrae 17 (QM F2316) derived from the uppermost Lower Cretaceous (upper Albian) Allaru Mudstone, 18 at a locality situated 77 km west-northwest of Richmond, Queensland. Prior to its rediscovery 19 in 2014, the type site was considered lost after failed attempts to relocate it in the 1970s. 20 Excavations at the site in 2014 and 2015 led to the recovery of several partial dorsal ribs and 21 fragments of presacral vertebrae, all of which clearly pertained to a single sauropod dinosaur. 2 22 The discovery of new material of the type individual of Austrosaurus mckillopi, in tandem 23 with a reassessment of the material collected in the 1930s, has facilitated the rearticulation of 24 the specimen.
