, 2021 In order to improve the poor Gondwana paleomagnetic database for Devonian times, detailed paleomagnetic analyses were performed on red chert-like rocks and partly silicified paleosols within the Lower Devonian Ikniouen level of the Tadrart Formation ...

XXX.—The Lower Devonian Fishes of Gemünden [PDF]
Transactions of the Royal Society of Edinburgh, 1905 Gemünden is situated in Rhenish Prussia, about eighteen miles to the west and slightly also to the south of Bingen, in the district known as the “Hunsrück,” and the rock in which the fishes to be described in this memoir occur is called the “Hunsrück Slates.”These Hunsrück slates belong to the Lower Devonian of the Rhenish area, and the position ...

The Anatomical Record, EarlyView.Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Middle to upper Devonian (givetian and frasnian) shallow-water carbonates of Western Europe: fades analysis and cyclicity [PDF]
, 1997 The Middle and Upper Devonian (Givetian-Frasnian) shallow-water carbonate facies of western Europe were deposited as a large-scale transgressive succession over continental facies of the Old Red Continent.

The Anatomical Record, EarlyView.Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Deep Underground Science and Engineering, EarlyView.This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

A lower Devonian point in the geological timescale.
GEOCHEMICAL JOURNAL, 1977 The Gocup Granite, in southeastern New South Wales, intrudes low-grade metasediments tentatively assigned to the Ludlovian on fragmentary conodont evidence, and is overlain by a unit rich in volcanic material but containing a good brachiopod fauna of lower to middle Siegenian age.
