Acritarchs of the Mesozoic of Ukraine

open access: yesVisnyk of V.N. Karazin Kharkiv National University, series Geology. Geography. Ecology, 2021
Introduction. Acritarchs are one of the orthostratigraphic groups of microfossils that are widely used in Proterozoic and Paleozoic biostratigraphy. In the Mesozoic period there is a decrease in this group, and this is due to certain reasons. Formulation of the problem.

The Ordovician acritarch genus Coryphidium [PDF]

open access: yesRevue de Micropaléontologie, 2008
The acritarch genus Coryphidium Vavrdova, 1972 is one of the most frequently recorded acritarch taxa in the Ordovician. The original diagnoses, stratigraphical ranges and geographical distribution of all Coryphidium species are critically evaluated in a review of published literature supplemented by studies of material from the British Isles, Belgium ...

An overview of Chinese Silurian acritarch research [PDF]

open access: yesCanadian Journal of Earth Sciences, 2016
The present paper reviews all investigations of Silurian acritarchs in China. Since Silurian acritarchs were first reported in China in 1978, significant progress has been made in Chinese Silurian acritarch research. A total of 30 scientific articles and theses have been published on Silurian acritarchs from China.

Organic‐walled microfossils from the Kistedalen Formation, Norway: acritarch chronostratigraphy of the Baltic Miaolingian and evolutionary trends of placoid acritarchs

open access: yesPapers in Palaeontology, 2022
AbstractNew acritarch data from the Kistedalen Formation based on two sections with continuous exposure enable us to establish the most detailed Miaolingian acritarch biozonation in Baltica to date. Six interval zones previously established in Gondwana, theEliasum llaniscum,Cristallinium cambriense,Adara alea,Timofeevia lancarae,Cristallinium ...
