Changes in land‐snail communities and steppe environments in the lower Rhône valley during the Lateglacial–Holocene transition

Boreas, EarlyView.
Land snail successions in the lower Rhône valley allow us to reconstruct the postglacial recolonization. From the Lateglacial period onwards, Mediterranean steppe communities appeared. The arrival of forest taxa was significantly delayed by aridity. The question of glacial refugia, both local and distant, primarily concerned Mediterranean species of ...

Delivering Sulfate to LNAPL Body for Enhanced Source Zone Depletion (ESZD)

Groundwater Monitoring &Remediation, EarlyView.
Abstract This field pilot study evaluates the feasibility of applying sulfate to a light non‐aqueous phase liquid (LNAPL) body for achieving enhanced source zone depletion (ESZD) at a refinery site. Two rounds of gypsum land application (GLA) delivered sulfate to an 8000 ft2 area encompassing LNAPL‐containing monitoring wells MW‐2 and MW‐3, while MW‐1 ...

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

Journal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

Journal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...
