Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Molecular dynamics simulations and fluorescence spectroscopy suggest reduced tryptophan‐to‐heme energy transfer facilitates lignin degradation in ClassII peroxidases

The FEBS Journal, EarlyView.
In lignin peroxidase and versatile peroxidase, low FRET from buried Trp to heme promotes long‐range electron transfer (LRET) from substrate to heme. This efficient electron flow is facilitated by reduced FRET competition. This mechanism likely evolved to enable the effective degradation of bulky, high‐redox‐potential lignin that cannot reach the enzyme'

DISCUSSION SUR L'AGE MURGABIEN OU MIDIEN DES SERIES PERMIENNES DU JEBEL TEBAGA (SUD DE LA TUNISIE)

Rivista Italiana di Paleontologia e Stratigrafia, 2017
A biostratigraphical analysis of Jebel Tebaga (Tunisia) is given. The Permian is divided in two zones: Afghanella zone of Middle-Upper Murgabian age; and Neoschwagerina, Yabeina and Dunbarula zone of Upper Murgabian- Lower Midian age, himself divided in ...

Upper Permian foraminifera from East Greenland

Bulletin Grønlands Geologiske Undersøgelse, 1996
Foraminiferal assemblages recorded from limestones of the Upper Permian Wegener Halvø Formation in the Wegener Halvø, Karstryggen and Clavering Ø areas of East Greenland mostly consist of the nodosariid genera Dentalina, Frondina, Geinitzina and Ichtyolaria, and the miliolid genera Agathammina and Calcitornella.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

Sedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Fault dislocations as fluid barriers of hydrocarbon deposits near salt domes in the Dnipro-Donets Depression, Ukraine

Geo&Bio
Within the Dnipro-Donets aulacogen, Devonian salt stocks (diapirs) are widely developed. The suprastock, interstock, and nearstock areas associated with these diapirs have consistently drawn the interest of researchers in the Dnipro-Donets Depression for

GINKGOPHYTES FROM THE UPPER PERMIAN OF THE BLETTERBACH GORGE (NORTHERN ITALY)

RIVISTA ITALIANA DI PALEONTOLOGIA E STRATIGRAFIA, 2014
Fossil evidence of late Palaeozoic ginkgophytes is rare; Palaeozoic floras in which ginkgophytes are abundant or represent a predominant element have not previously been described. The late Permian (Lopingian) flora from the Gröden/Val Gardena Sandstone of the Bletterbach gorge in the Dolomites (northern Italy) contains an unusually large proportion of

New insects from the Permian of Catalonia (Spain) predate the early diversification of Triassic clades adapted to arid environments (Grylloblattodea, Probnidae, Dictyoptera) [PDF]

Fossil Record
Probnis sauvanyaensis sp. nov., the first representative of the ‘grylloblattodean’ family Probnidae from the Iberian Peninsula, is described from the middle to ?upper Permian outcrop of Sauvanyà in the Catalan Pyrenees.
