Development of a Regional Stratigraphic Framework For Upper Devonian Reef Complexes Using Integrated Chronostratigraphy: Lennard Shelf, Canning Basin, Western Australia [PDF]

open access: yes, 2013
Questions regarding heterogeneity and architecture of reefal carbonate platform systems may be resolved by well-constrained chronostratigraphic frameworks, developed from the integration of multiple independent signals in the rock record.

Methods in taxonomy and biostratigraphy, and some note on chronostratigraphy: the Devonian–Carboniferous Boundary.

open access: yes, 2011
The Devonian–Carboniferous Boundary (DCB) was defined in the section La Serre trench E’ (Montagne Noire, France) at the base of bed 89. The criterion chosen for its definition was entry of the conodont Siphonodella sulcata.

Devonian-Carboniferous boundary beds in the Vorkuta transverse uplift (Bolshaya Usa River)

open access: yes, 2018
The paper contains multidisciplinary data on the lithology and palaeontology of the Devonian–Carboniferous boundary beds in the shallow-water facies in the Bolshaya Usa River section (Vorkuta Uplift). A recent discussion on the position and marker of the

The walls boundary fault zone and the MØre TrØndelag fault complex:: a case study of two reactivated fault zones. [PDF]

open access: yes, 2001
It is commonly observed that ancient faults or shear zones can become reactivated again and again, either within the same or even superimposed tectonic episodes, yet millions of years apart.

Paleobiogeography of Devonian vertebrates

open access: yes, 1992
Five distinctive vertebrate faunas characterised by endemic taxa can be recognised for the Early Devonian (Euramerica, Siberia, Tuva, China, and East Gondwana).

Coral Photosymbiosis on Mid-Devonian Reefs

open access: yes, 2023
The ability of scleractinian corals to thrive in the oligotrophic (low-nutrient, low-productivity) surface waters of the tropical ocean is commonly attributed to their symbiotic relationship with photosynthetic dinoflagellates1,2.

Stratigraphic significance of Devonian brachiopods of the Urals

open access: yesЛитосфера, 2017
The article considers the history of the formation of the regional stratigraphic scale of the Devonian system of the Urals, historically developed on the basis of the study of benthic fauna (mainly brachiopods).

Eifelian (Middle Devonian) to Early Frasnian (Late Devonian) conodonts and strata in the Spanish Central Pyrenees: Global correlations and effects of climatic fluctuations in the biota

open access: yes
The interval between the late Eifelian and early Frasnian was marked by significant paleoenvironmental instability, including major evolutionary, eustatic, and biotic events.
