Late Devonian (Frasnian–Famennian) palynomorphs from the Padeha and Bahram Formations of Shahzadeh Mohammad section, northwest of Kerman, Iran [PDF]

Acta Palaeobotanica, 2022
A diverse and well-preserved microphytoplankton assemblage is reported from a measured section of Frasnian–Famennian (Upper Devonian) Padeha and Bahram Formations in Shahzadeh Mohammad area, northwestern Kerman, southeast Iran. The palynoflora assemblage

Frasnian [PDF]

, 2006
The name Frasnian, which comes from the locality of Frasnes near Couvin in Belgium, was introduced by Gosselet in 1879 and was formally retained for the lower stage of the Upper Devonian by the Subcommission on Devonian Stratigraphy in 1981. The modern definition of the Frasnian is based on conodonts and the historical background of the stage is ...

Frasnian carbonate mounds from Belgium:sedimentology and palaeoceanography [PDF]

Geological Society, London, Special Publications, 2007
Abstract The facies architecture, sedimentary dynamics and palaeogeographic evolution were reconstructed for a number of middle-late Frasnian carbonate mounds from the south side of the Dinant Synclinorium (Belgium). Nine facies were recognized in the buildups, each characterized by a specific range of textures and assemblage of organisms ...

Biostratigraphy of the Frasnian stage by radiolarian evidence

, 2001
Revising Frasnian radiolarians, we established three new radiolarian zones within this stage. These are the Helenifore gogoense-Retisphaera concinna Zone of the lower Frasnian, Moskovistella allbororum-Ceratoikiscum ukhtensis Zone of the middle Frasnian, and Bientactinosphaera egindyensis - Polyentactinia circumretia Zone of the upper Frasnian.

UPPER FRASNIAN (UPPER DEVONIAN) BRYOZOANS IN PROXIMAL FACIES OF SOUTHERN BELGIUM

Rivista Italiana di Paleontologia e Stratigrafia, 2015
Seven bryozoan species are described from the shallow-water Aisemont and Lambermont formations (upper rhenana Conodont zone, upper Frasnian) in southern Belgium. The studied interval is situated between the lower and upper Kellwasser events.

LATE DEVONIAN CONODONTS FROM THE HOJEDK SECTION, KERMAN PROVINCE, SOUTHEASTERN IRAN

Rivista Italiana di Paleontologia e Stratigrafia, 2008
Conodonts (34 species and subspecies) from the Hojedk section north of Kerman span the late Givetian to early Famennian. The new data suggest that Devonian biostromes in central and eastern Iran were deposited on differing levels, and that the currently ...

Palynology and geochemistry of the Frasnian global transgression in the Parnaíba Basin, Brazil [PDF]

Review of Palaeobotany and Palynology, 2021
Abstract An integrated palynological and geochemical approach has been initiated to date and to precise the geochemical events of the Pimenteiras Formation, in the Late Devonian from the Parnaiba Basin, Brazil. Based on good biostratigraphic markers and presence of index species among miospores, acritarchs and chitinozoa, the investigated sequences ...
