Constraints on the evolution of Taranaki Fault from thermochronology and basin analysis: Implications for the Taranaki Fault play [PDF]

open access: yes, 2004
Taranaki Fault is the major structure defining the eastern margin of Taranaki Basin and marks the juxtaposition of basement with the Late Cretaceous-Paleogene succession in the basin.

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

open access: yesThe Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Quaternary sediment patterns in the Weddell Sea: relations and environmental conditions [PDF]

open access: yes, 1988
Sediment patterns such as texture, composition, and facies from three selected areas of the Antarctic continental margin of the Weddell Sea are discussed in relation to environmental variations of the Quaternary hydrosphere and kryosphere.

Elliptic Fourier analysis as a tool for the taxonomic identification of isolated theropod pedal phalanges

open access: yesThe Anatomical Record, EarlyView.
Abstract Studies of Upper Cretaceous deposits in North America have provided invaluable insights into the continental ecosystems of this time. Theropod (Saurischia, Dinosauria) pedal phalanges are commonplace in these deposits but can be difficult to identify at a finer taxonomic resolution.

Sea-air CO2 fluxes along the Brazilian continental margin

open access: yesOcean and Coastal Research
Measurements of the marine carbonate system on tropical and subtropical continental margins are poorly distributed in space and time, with many uncertainties persisting regarding the role of carbon exchanges at the ocean-atmosphere interface in these ...

Cardiac morphological and morphometric analysis of Ardea alba

open access: yesThe Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Data report: Seismic structure beneath the North Cascadia drilling transect of IODP Expedition 311 [PDF]

open access: yes, 2006
Between 1999 and 2004, new seismic data became available for the study of gas hydrates on the northern Cascadia margin. These data consist of multi- and single-channel data with two- and partly three-dimensional subsurface coverage and were acquired and ...
