Chitinozoans from the upper Frasnian (Upper Devonian) of Armenia : biostratigraphical and palaeobiogeographical implications

This paper marks the first systematic study of chitinozoans from the Upper Devonian succession of Armenia. The examined material, derived from the upper Frasnian strata of the Ertych section, contributes to our understanding of the diversity of ...

Biostratigraphy and palaeogeography of lower Devonian Chitinozoans, from East and West Moesia, Romania [PDF]

, 2005
The knowledge on the biostratigraphy of Moesia has been supplemented based on chitinozoan assemblages in two boreholes, one from East Moesia and the second one from West Moesia. Previous contributions on chitinozoans, acritarchs and miospores, using only

A spike in malformed chitinozoans announces the Ireviken Ocean Anoxic event in the lower Wenlock☆

The Silurian record is punctuated by several large, positive stable carbon isotope excursions that coincide with extinction events. Increasingly, these events are interpreted as Silurian Ocean Anoxic Events (OAEs). Malformed chitinozoans (extinct organic-

Les microfossiles (Chitinozoaires et Acritarches) des schistes du Tazekka au Maroc oriental

, 1982
Acritarchs and Chitinozoans of Lower Ordovician age (Arenigian-Llanvirnian) were found in the schists of the Tazekka (Morocco), previously dated on the Lower Carboniferous (Rauscher et al., 1982). These microfossils are described and illustrated here.
