Early Toarcian Oceanic Anoxic Event): New Microfossils from the Dudelange Drill Core, Luxembourg
Downloaded from http://sp.lyellcollection.org/ by guest on September 29, 2021 Brittlestar diversity at the dawn of the Jenkyns Event (early Toarcian Oceanic Anoxic Event): new microfossils from the Dudelange drill core, Luxembourg Ben Thuy* and Lea D. Numberger-Thuy Department of Palaeontology, Natural History Museum Luxembourg, 25 rue Münster, 2160 Luxembourg City, Luxembourg BT, 0000-0001-8231-9565; LDN-T, 0000-0001-6097-995X *Correspondence: [email protected] Abstract: Ophiuroids, the slender-armed cousins of starfish, constitute an important component of modern marine benthos and have been used successfully in the exploration of (palaeo)-ecological and evolutionary trends, yet their fossil record is still poorly known. One of the major gaps in the known palaeobiodiversity of this group coincides with a global palaeoenvironmental crisis during the early Toarcian (Early Jurassic, 183 myr ago), known as the Jenkyns Event. Here we describe ophiuroid remains retrieved from a series of sam- ples from the Dudelange (Luxembourg) drill core, which spans the lower part of the Toarcian, between the top of the Pliensbachian and the onset of the Jenkyns Event. A total of 21 species are recorded, including three new genera and 12 new species. Ophiuroid diversity and abundance fluctuate in parallel with depositional facies, with lowest values coinciding with black shales. Highest diversities, including exceptional occurrences of taxa nowadays restricted to deep-sea areas, are recorded from just below the black shales, corresponding to the onset of the Jenkyns Event. Our results show that even small (100 g) bulk sediment samples retrieved from drill cores can yield numerous identifiable ophiuroid remains, thus unlocking this group for the study of faunal change across palaeoenvironmental crises. -
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. -
Dinosaurs (Reptilia, Archosauria) at Museo De La Plata, Argentina: Annotated Catalogue of the Type Material and Antarctic Specimens
Palaeontologia Electronica palaeo-electronica.org Dinosaurs (Reptilia, Archosauria) at Museo de La Plata, Argentina: annotated catalogue of the type material and Antarctic specimens Alejandro Otero and Marcelo Reguero ABSTRACT A commented-illustrated catalogue of non-avian dinosaurs housed at Museo de La Plata, Argentina is presented. This represents the first commented catalogue of the La Plata Museum dinosaurs to be published. This includes the type material as well as Antarctic specimens. The arrangement of the material was made in a phylogenetic fashion, including systematic rank, type material, referred specimens, geographic and stratigraphic location, and comments/remarks, when necessary. A total of 13 type specimens of non-avian dinosaurs are housed at the collection of Museo de La Plata, including eight sauropods, one theropod, one ornithischian, and three ichnotaxa. There are four Antarctic specimens, one of which is a holotype, whereas other corresponds to the first sauropod dinosaur registered for that continent. Alejandro Otero.

Acta Geologica Polonica, 55 (3), 269-282. Warszawa. An assemblage of feather stars or comatulids (free-living crinoids of the order Comatulida AH. CLI\RK, 1908) is reported for the first time from Upper Jurassic sequences of Poland, precisely from Lower Kimmeridgian strata of the Holy Cross Mountains. The major part of this assemblage comes from oolitic deposits exposed at Malogoszcz Quarry, others from oyster (Actinostreon, and Nanogyra) shellbeds higher up section at Malogoszcz, as well as from the coeval strata of the Karsy section. Taxonomically recognizable skeleton elements such as calyces, isolated een trodorsals and radials are here assigned to seven taxa, three of which are new to science: Comatulina malogoslialla sp.nov., Palaeocomaster learsensis sp.nov., and Solanocrinites sanctacruccnsis sp.nov. The majority of the material available was contained in burrows made by some ancestral stock of alpheid shrimp, closely comparable to those of present-day snapping shrimp (genus Alpheus WEBER, 1795), and its allies. These burrows, situated at the tops of oolitic shoals/banks at Malogoszcz, casually served both as habitats of cryptic faunas (mostly comatulids, dwarf-sized gastropods) and as preservational/taphonomic traps for others, primarily echinoderms (ten taxa of echinoids, three stalked crinoids, two ophiuroids, one asteroid) swept into by highly agitated waters, most likely during storms, to pro duce an Echinodermenlagerstdlte. -
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.

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.
