Stratigraphy of the Upper Devonian - Lower Carboniferous of south-west of Lyzha-Kyrtael swell (Pechora Plate eastward) [PDF]
A new local stratigraphic scheme is proposed for the upper Famennian - Serpukhovian interval of the south-west of Lyzha-Kyrtael Swell. The stratigraphic sequence is composed of the Famennian carbonates of the Kamenka Formation, the Famennian - middle ...

In a complex and diverse reef community composition the biogenic nature of the deposition of the carbonate material is the most evident. Biotic crises, after which a significant evolutionary update of the organic world took place, also affected ...

A new assessment of the Late Devonian antiarchan fish Bothriolepis leptocheira from South Timan (Russia) and the biotic crisis near the Frasnian–Famennian boundary [PDF]
The species of the Late Devonian, earliest Famennian placoderm fish Bothriolepis jeremejevi has been downranked to subspecies Bothriolepis leptocheira jeremejevi comb. nov.

SYSTEMATIC POSITION OF ANTIARCHS (VERTEBRATA, PLACODERMI) FROM THE FAMENNIAN OF TVER REGION, RUSSIA
New materials of the placoderm fish Bothriolepis heckeri Luksеvics from the Famennian of the Bilovo locality (Tver Region) are studied. This species is very similar to Livnolepis zadonica (H.Obrucheva) in the structure of cranial and postcranial armours ...

Rock stress state influence on permeability of carbonate reservoirs
The relevance of the discussedissue is caused by the fact that the oil fields of the Perm region are determined by the widespread occurrence of fractures in carbonate reservoirs and the influence of fractured rocks on oil filtration in the reservoir. The

Carbon isotopic composition of the Early Famennian conodonts and host carbonates of the Izma Formation (South Timan) [PDF]
The variations in the carbon isotope composition of conodonts and host carbonates have been studied on material from the Lower Famennian of the southern part of the Timan-Pechora petroleum Province.

Famennian (Upper Devonian) conodont zonation: revised global standard [PDF]
The revision of the Famennian part of the “Late Devonian Standard Conodont Zonation” is based on the inequivalence between biozones and time, and the rejection of the presumed single phyletic concept on which the previous zonation was based. It is also intended to simplify the zonation, eliminating the zonal groups named after only one taxon, and ...
