- Abstract:
- ... The sedimentology, geomorphology and chronology of late Quaternary fluvial landforms and sedimentary sequences within the Mulgrave River catchment in northeast Queensland suggest that episodic stripping or wholesale erosion of Holocene floodplains is a major mode of sediment delivery to the Great Barrier Reef lagoon. The last major phase of Holocene valley sediment removal likely occurred sometime ...

- Abstract:

Hollow microtubular structures with pyrite grains at their termini have been found in phosphatocopines (Hesslandona toreborgensis and Hesslandona cf. angustata) from the late Cambrian of northern Poland, and in the metacopine ostracod Cytherellina submagna from the Early Devonian of Podolia, Ukraine.The Cambrian phosphatocopines are secondarily phosphatised and microtubes (5–20μm in diameter) are ...

- Abstract:
- ... The Prince Creek Formation of northern Alaska is the most abundant source of polar dinosaur remains in the world, and now, corroborating data from this well-studied rock unit allow for making inferences about the paleoecological preferences for these extinct polar animals. The rock unit records high-latitude, alluvial sedimentation and soil formation on a low-gradient, muddy coastal plain. Compoun ...

This study documents and compares the planktic foraminiferal records, carbonate dissolution effects, stable isotopes, and magnetic susceptibility in France (Bidart), Austria (Gamsbach) and Tunisia (Elles) in order to expl ...

Turnabout Ridge, a remote outcrop belt in the Beardmore Glacier Region of the Central Transantarctic Mountains, comprises subglacial–glaciomarine deposits of the Pagoda Formation (Fm) overlain by a postglacial deltaic succession of the Mackellar–Fairchild formations (fms). Four depositional environments were identified in the Mackellar–Fairchild fms: 1) prodelta to distal-delta-front deposits that ...

- Abstract:
- ... Waterholes in African savanna ecosystems are often locations of carnivore serial predation. At Ngamo Pan, located in Hwange National Park, Zimbabwe, predators take advantage of natural and artificial waterholes to ambush prey, resulting in the a vast accumulation of large mammal bones across the local landscape. Lions are presumed responsible for many predation occurrences surrounding waterhole lo ...

Investigations of calcareous nannoplankton assemblages including species richness and abundance data were performed across the K–Pg boundary interval at Agost (SE Spain), between −100cm and +100cm, below and, respectively, above the boundary, at a considerable high resolution averaging 2cm. From a total of 98 species of the Upper Maastrichtian, only 13 survived mass extinction, while the rest of t ...

Measuring the abundance and size distribution of framboidal and euhedral microscopic crystals of pyrite has proven to be an effective method to determine the paleoenvironmental conditions in sedimentary rocks bearing these minerals. However, micropyrites can be found in other geological environments as well, such as low-grade metamorphic and hydrothermal. In these cases, their sizes and distributi ...

- Abstract:
- ... Inshore reefs on Australia's Great Barrier Reef (GBR) are widely argued to be in decline, although recent reports suggest that some may be more resilient than traditionally assumed. Resolution of this debate requires long-term insights into past reef development and variability to provide context for the assessment of present reef condition. Long-term reef growth histories can preserve extended re ...

- Abstract:

It started at the Julian 1–2 boundary and lasted approximately until the latest Julian or early Tuvalian. In the Tethys this is reflected by a change from limestone deposits to, first, organic rich mudstones and then to siliciclasti ...

Most of the Pleistocene species of Equus from Mexico have been considered to be grazers and highly specialized on the basis of their craniodental features, and therefore analogous to their modern relatives from an ecological point of view. Here we rely on dental wear analyses of three different species of Rancholabrean Equus that exhibit differences in limb proportions and body mass and occurred i ...
