Cambro-Ordovician microorganisms: acritarchs and endoliths

, 2005
Organic-walled microfossils are abundant and taxonomically diverse in Cambrian-Ordovician strata; some are important for biostratigraphy and for the correlation of geological successions. New assemblages of Cambrian-Ordovician acritarchs from Kolguev Island, Arctic Russia and Middle Cambrian ichnofossils of endoliths from Peary Land, North Greenland ...

Proterozoic acritarchs and divergences of green microalgae

, 2010
The morphology of microfossils with resistant cell walls, their ornamentation and functionally identifiable structures are the first source of information used to assess their biological affinities. Difficulties in relying on morphology alone due to the problem of convergent morphology may be resolved by the ultrastructure of the cell wall and its ...

Acritarchs from the Duolbagáisa and Kistedalen formations (Cambrian Series 2-3), Digermulen Peninsula, northern Norway

, 2015
New information on acritarchs from the upper part of the Duolbagáisa Fm., and the lower part of the Kistedalen Fm., on SE Digermulen Peninsula, northern Norway, adds biostratigraphical control to previous studies on trilobites and acritarchs. Levels with

Neoproterozoic (Ediacaran) radiation of acritarchs – a new record

, 2004
The terminal Neoproterozoic radiation of planktonic photosynthetic microbiota (acritarchs) is one of the most significant evolutionary events of the time, including diversification of prokaryotic cyanobacteria and eukaryotic green and brown algae, the ...
