Stratigraphy and Geological Correlation, 2021 The complete sections of the Lower and Upper Vendian of the East European Platform were opened in the boreholes of Belarus. This allows us to consider this region as a stratotype area. In order to update the paleontological characteristics of the Vendian,

Diversity of the Vendian fossils of Podillia (Western Ukraine)
Geo&Bio, 2020 Diversity ofVendian fossil associations is a common feature. The diversity depends on many factors: firstly, physical conditions in the basin, in which animals lived (i.e.

New palaeomagnetic result from Vendian red sediments in Cisbaikalia and the problem of the relationship of Siberia and Laurentia in the Vendian [PDF]
Geophysical Journal International, 2000 A palaeomagnetic study of Vendian red sediments from the Lena River section on the western margin of Lake Baikal in the region of Cisbaikalia (54°N, 108°E) has isolated a stable remanence with direction D = 296.3°, I = −27.7° (high-temperature component) and a corresponding pole of 2.7°S, 168.2°E.

Developmental principles: fact or fiction. [PDF]
ScientificWorldJournal, 2012 While still at school, most of us are deeply impressed by the underlying principles that so beautifully explain why the chemical elements are ordered as they are in the periodic table, and may wonder, with the theoretician Brian Goodwin, “whether there might be equally powerful principles that account for the awe-inspiring diversity of body forms in ...

Papers in Palaeontology, Volume 9, Issue 6, November/December 2023., 2023 Abstract Fine‐grained, siliciclastic units of the >1642 ± 3.9 Ma late Palaeoproterozoic Limbunya Group, Birrindudu Basin host rich, well‐preserved organic‐walled microfossil assemblages that include members of total‐group eukaryotes. These assemblages include taxa characteristic of this interval such as Tappania plana and Satka favosa, as well as less ...

Ediacaran–Cambrian bioturbation did not extensively oxygenate sediments in shallow marine ecosystems
Geobiology, Volume 21, Issue 4, Page 435-453, July 2023., 2023 Abstract The radiation of bioturbation during the Ediacaran–Cambrian transition has long been hypothesized to have oxygenated sediments, triggering an expansion of the habitable benthic zone and promoting increased infaunal tiering in early Paleozoic benthic communities.

Seaward‐Dipping Reflector Influence on Seafloor Magnetostratigraphy—A Pelotas Basin View
Geophysical Research Letters, Volume 49, Issue 23, 16 December 2022., 2022 Abstract Previous works used marine magnetic survey data and interpreted magnetic anomalies related to seaward‐dipping reflectors (SDRs) as oceanic crust or SDR age constraints in the South Atlantic Ocean. However, we advise against using SDR‐related magnetic anomalies to constrain ages because of the mostly low‐dipping geometry causing the overlapping
