Review of Dysmorphoptilidae Handlirsch (Hemiptera: Cicadomorpha) from the Argentinean Triassic, with description of a new subfamily, and a new species [PDF]

open access: yes, 2006
This contribution presents new fossil insect taxa of the order Hemiptera (Cicadomorpha, Dysmorphoptilidae, Gallegomorphoptilinae subfam. n.) from the Ischichuca Formation (late Middle Triassic to early Late Triassic) from La Rioja Province (Argentina ...

Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
New U–Pb zircon dating shows the Rewan Group was deposited between ~250 and 233 million years ago and that sedimentation shifted across the basin through time, with earlier deposition in the foredeep and later deposition in the back bulge. Testing multiple dating approaches and grain‐selection strategies improves confidence in these age estimates and ...

Observations on the Upper Permian of Wegener Halvø, East Greenland

open access: yesRapport Grønlands Geologiske Undersøgelse, 1979
The Upper Permian sediments of East Greenland are exposed from Scoresby Land in the south to Clavering Ø in the north (fig. 30). The deposits on Wegener Halvø appear to be situated on the eastern side of the southern end of an elongated, approximately 80 km wide, sedimentary basin (Birkelund & Perch-Nielsen, 1976).

Prediction of Fault and Fracture Density From Seismic Attributes and Machine Learning Models Calibrated With Borehole Image Logs

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
This study integrates post‐stack seismic attributes with a CNN‐based workflow to characterize sub‐seismic deformation in shale gas reservoirs. A near‐linear correlation is established between seismic characterization methods and borehole deformation counts.

The caliph and the falcons: a ninth‐century history from Iceland to Iraq

open access: yesEarly Medieval Europe, Volume 34, Issue 2, Page 299-322, May 2026.
In the late ninth and early tenth centuries, an extraordinary number of falcons were given to the ʿAbbāsid caliphs in Baghdad, many of which were white. Gifts from competing dynasties in the northern provinces of the Caliphate, at least some of these birds were almost certainly gyrfalcons from near the Arctic Circle.

The Middle and Upper Permian deposits in Gorski Kotar: facts and misconceptions

open access: yesGeologia Croatica, 1997
The frequent occurrence of sandstones and other coarse-grained sedimentary rocks in Gorski Kotar indicates molasse-type sedimentation as a consequence of the intensive erosion of an uplifted terrain in a tectonically active area. The indirect assumptions indicate that the age of the Gorski Kotar Palaeozoic complex, with the exception of a limited ...
