The last Frasnian Atrypida (Brachiopoda) in southern Belgium [PDF]

open access: yes, 1998
The last representatives of the order Atrypida on the southern flank of the Dinant Synclinorium (Vaulx-Nismes area) in Belgium belong to Costatrypa, Spinatrypa, Spinatrypina (?Spinatrypina), Spinatrypina (Exatrypa), Iowatrypa, ?Waiotrypa, Desquamatia ...

Trace element variations in the Middle Frasnian punctata zone (Late Devonian) in the western Canada sedimentary basin: changes in oceanic bioproductivity and paleoredox spurred by a pulse of terrestrial afforestation? [PDF]

open access: yes, 2010
The ‘punctata Event’ (Early–Middle Frasnian transition, Late Devonian) was recently recognized as yet another episode of major geochemical perturbations associated with the Middle-Late Devonian ecosystem readjustments which culminated in the Frasnian ...

Les Entomozoacea (Ostracodes) du Frasnien de l’extreme occidentale du bord sud du bassin de Dinant, Belgique [PDF]

open access: yes, 1982
An abundant and relatively well-preserved Frasnian entomozoid fauna occurs in the westernmost sequences of the southern part of the Dinant Basin. Fifteen species have been identified of which five are described.

Chitinozoan response to the ‘Kellwasser events’: population dynamics and morphological deformities across the Frasnian–Famennian mass extinction

open access: yesPapers in Palaeontology
AbstractFossil (zoo)plankton dynamics during Devonian ocean‐anoxic and extinction events can shed light on the palaeoceanographic and geochemical processes that shaped the middle Palaeozoic biosphere. However, datasets on (Upper) Devonian marine palynology, illustrating such dynamics, remain underexplored.
