The Late Devonian (Frasnian/Famenian) mass extinction : a proposed test of the glaciation hypothesis

, 2014
It is argued in this paper that late Frasnian global cooling was the first step in the onset of the Late Palaeozoic Ice Age, and that the late Frasnian extinctions are analogous to the early Oligocene (Oi-1) extinctions that took place in the first step ...

A NEW SPECIES OF CYRTOSPIRIFER (BRACHIOPODA) FROM THE MIDDLE DEVONIAN OF THE WESTERN SAHARA (NORTHWESTERN AFRICA)

Rivista Italiana di Paleontologia e Stratigrafia, 2011
A new species of Cyrtospirifer is described from the Middle to Upper Givetian of the Western Sahara (Northwest Africa). Cyrtospirifer tindoufensis new species differs in its smaller number and coarser medial and flank plications and equibiconvex shell ...

Diverse depositional and geochemical signatures of the Frasnian-Famennian global event in western Thailand reveal palaeotethyan vs. Western Australian geotectonic affinities

Journal of Asian Earth Sciences: X, 2019
Two studied sections of the Frasnian-Famennian (F-F) boundary beds in western Thailand differ significantly in their depositional and geochemical characteristics.

Specific features of carbon and oxygen stable isotopes (δ13C and δ18O) geochemistry in the isolated carbonate platform section on the east of the Urals (the Famennian and Tournaisian Stages)

Литосфера, 2016
New data about the stable carbon and oxygen isotopic composition for the Frasnian/Famennian and Devonian/Carboniferous boundary intervals, as well as for middle and upper parts of the Tournasian Stage (the Lower Carboniferous), are represented in this ...

Early Frasnian bioherms in the Holy Cross Mts

, 2020
The Frasnian bioherms exposed along the southern limb of the Gałęzice syneline in the Holy Cross Mts, Central Poland, occur in the highest part of the stromatoporoid-coral sequence, and their facies equivalent are chiefly the·coral biostromes·of the Upper Sitkówka Beds.
